Crying at a Buddhist Funeral, by Adam Goldberg


In the following guest-post, Adam Goldberg reflects on the meaning of equanimity in the face of one of life's most difficult moments. Adam is spending one year in Asia, exploring how Buddhism is interpreted and understood in the face of conflict and violence and, ultimately, how it is used as a vehicle for building peace.

Crying at a Buddhist Funeral

The room is a blurry haze; the bright orange of monastic robes saturate her vision and her feet seem to hover as she moves to an open chair. Her mind is distant and she can’t feel a thing but for a sensation of cold emptiness that presses against her chest, growing and growing, threatening to freeze her. She raises her eyes – they are heavy and wet with tears – but the faces of those around her are tranquil; at ease, as if someone has not just died.

*****

Having just finished a two week Vipassana meditation retreat in Burma, I was impressed by the calm, serene and balanced composure of the Sayadaws (teachers). I couldn’t help but wonder, would they cry at a funeral? What keeps equanimity from becoming indifference, or rather, isn’t equanimity indifference?

The mental state of upekkha, equanimity, is essential to attain enlightenment. It enables us to maintain mindfulness (sati) in every situation. We could be eating good food or tasteless food, experiencing immense pain or pleasure, cursed or praised, and upekkha will protect us from being carried away by these experiences. Nonattachment is unbroken in its presence, and Right View is affirmed as we recall that everything breaks down to nama-rupa, or mind-matter phenomena which arises and ceases in each moment. One technique I have come across to generate equanimity is to think of someone’s misfortune or fortune as the reaping of his or her kamma.

Wait. What does that really mean? If a bus is out of control and unable to steer itself away from an oblivious man, should we warn him? If we don’t, is it not because of his kamma that he will be killed and his own fault? This is simplistic, I know, but it gets to the point – if bad fortune is due to that person’s bad kamma, should we feel responsible to help those who are vulnerable? If so, where does that sense of responsibility come from?

In Sayadaw U Pandita’s book, “In This Very Life”, he writes “equanimity is not insensitivity, indifference or apathy. It is simply nonpreferential. Under its influence, one does not push aside the things one dislikes nor grasps at things one prefers. The mind rests in an attitude of balance and acceptance of things as they are.” If not insensitivity, then is equanimity sensitivity? If not indifference and apathy, is it caring? And finally, how can we be “nonpreferential” while exercising another of the sublime mental states (Brahmin Vihara) – compassion? To me, compassion (karuna) necessarily implies a preference, namely that I am unpleased with the current situation and wish to improve it.

In U Pandita’s discourse, he emphasizes the importance of cultivating compassion alongside wisdom, so action is be guided with precise aim to effectuate positive change. Compassion without wisdom can be extremely dangerous; we act with a desire to do good, but in fact cause more harm! We may justify the impact of our actions by proudly standing behind our intentions. But as the saying goes, “the road to hell is paved with good intentions.” Clearly, compassion isn’t enough.
Wisdom (panna) and equanimity go hand-in-hand. One of the three characteristics of existence (tilakkhana) is anatta, or non-self. Anatta is a profound concept and definitions like “devoid of an inherent existence” can be misleadingly vague. I will not elaborate on anatta here, but I encourage you to see link below for an in-depth description. Instead, I’d like to point out the implication of anatta: we are not truly in control of ourselves or the world around us; we cannot stop aging, nor can we control the choices our loved ones make. Some things will not go as planned no matter how hard we try; inevitably yielding results that can be disappointing. And it is undeniable that the more we invest ourselves in effort, the more attached we can become to the result. Anatta reminds us the folly of such investment.

Understanding this aspect of anatta, equanimity is steadfast and strong. Actions are not influenced by attachments but guided by the clarity of wisdom. Neither “success” nor “failure” distracts us from our goal, allowing us to reassess and invest ourselves in the situation free from emotional antagonisms. Fortified by equanimity, compassion takes its noblest form: accurate, effective, and unquestionably selfless.

Empty of what?

One of the more difficult concepts in Buddhism - one of the most fundamental as well as perhaps the most widely misunderstood - is rendered in English as emptiness. In Zen it is taught with the Japanese word Ku. Many people misunderstand emptiness as complete non-existence. When I first came across this idea as an undergraduate, I imagined it was teaching that the phenomenal world was a sort of hologram hiding a sort of vast, cosmic nothingness. The term is sometimes translated as void, or worse The Void, which doesn't help. The word in English also has negative connotations implying a destitution of meaning or value or feeling. Is it any wonder that people think Buddhism is nihilistic? Is this misunderstanding of emptiness just a problem of its translation into English?

The concept that is rendered as Ku in Japanese derives from the Chinese Wu , which comes from Sunyata (Sanskrit), which in turn comes from Sunnata (Pali). The adjective in Pali is Sunna (empty). Have we lost the meaning in this game of Chinese whispers? Sunnata has the same connotation of ordinary physical emptiness in Pali as emptiness has in English - and it was sometimes misunderstood in similar ways. Confusion about the meaning was common even in the time of Buddha it appears and Buddhism has at times been accused of nihilism through much of its history. But in 'Dhamma language' emptiness doesn't mean total nonexistence, or nihilism. It means something quite specific, which can be expressed in positive as well as negative terms, but which is an experience that is beyond words and even concepts. It is the transcendence of the narrow identification of self to an egoless experience of reality without borders, the experience of samadhi - the non-dualistic state of consciousness seen as a pre-cursor to Nirvana.

Originally Sunna referred directly to the anatta (no self-nature) doctrine.

According to orthodox religious and philosophical thought at the time Buddha lived, each and every living being had its own unchanging 'soul' or essence - the atman - which was or became unified with the cosmic Atman (according to some the same as Brahman) on enlightenment. Buddha was contradicting this doctrine - anatta/anatman was a denial of atta/ atman - and sunna was an expression of this. It wasn't a denial of mind or consciousness or the sense of self, it was a denial of a real, enduring, independent, self-existent essence or soul.

In the Suñña Sutta, Ananda asks the Buddha, "It is said that the world is empty, the world is empty, lord. In what respect is it said that the world is empty?" The Buddha replied, "Insofar as it is empty of a self or of anything pertaining to a self: Thus it is said, Ananda, that the world is empty."

So, emptiness is not total nonexistence, but refers specifically to the absence of an atman - an ultimately real self, essence or identity. And describes reality in terms of interdependence rather than self-standing existences. But what relevance does this have to non-Brahmanists and non-metaphysicians?

Such doctrines as the Atman doctrine are really an intellectual expression of the ordinary human way of thinking of life in terms of enduring entities. The identities of things in the world are conventions of the human mind and society. We project these perceived identities outwards onto the universe itself, as if the universe really was divided up into discreet and abiding objects. At best, we see these 'things' as having changing relationships and properties, but nevertheless, an enduring identity. Buddhism teaches that the notion of entities is nominal or conventional. It is a necessary feature of thought and language that we treat identifiable aspects of reality as if they have a continuous existence - even if we acknowledge that this existence is characterised by change. Many computer programming languages are said to be 'object orientated' in the sense that they handle data in terms of identities or objects which have certain properties at any given time. The way that human beings think is remarkably similar to this in some ways. In terms of Buddhist philosophy, we confuse conventional reality with ultimate reality - that is, we confuse the nominal with the actual. No doubt it is a functional, pragmatic way to deal with information, but not a true reflection of reality, which as modern physics tells us, is a seamless and deeply interdependent flux - an evolving matrix of processes within processes. According to Buddhism it is this disparity between out attachment to the notion of enduring entities and the transience of reality, which causes the suffering that we experience from day to day.

Why do the original teachings emphasise this negative description, in terms of absence? It was framed in this way, to respond to the eternalist atman doctrine while perhaps minimising the chance of being interpreted as a new set of statements about the essence of reality. The power of this tendency to reify reality - to project our concepts of identity as if they existed externally - means that we may see even a teaching of inter-dependence in terms of a network of relationships between entities, when really it is only the mind that creates the existence of any entities or even relationships - reality is a seamless - and ultimately indescribable - whole. This is why, to avid nihilistic misunderstandings, some modern teachers describe emptiness in terms of openness or fullness - because phenomena are empty of that which would separate or confine them - a self-existent identity or essence.

Buddha taught that all phenomena are characterised by three qualities - the Three Marks of Existence:
Dukkha (Sanskrit duhkha) or unsatisfactoriness. Nothing found in the physical world or even the psychological realm can bring lasting deep satisfaction.

Anicca (Sanskrit anitya) or impermanence. This refers not only to the fact that all conditioned things eventually cease to exist, but also that all conditioned things are in a constant state of flux. (Visualize a leaf growing on a tree. It dies and falls off the tree but is soon replaced by a new leaf.)

Anatta (Sanskrit anatman) impersonality, or non-Self. The human personality, "soul", or Self, is a conventional appellation applied to the assembly of physical and psychological components, each individually subject to constant flux; there is no central core (or essence); this is somewhat similar to a bundle theory of mind or soul.
Source
These characteristics are inter-dependent: it is because things lack an independent essence, that they are in a constant state of change; it is because we hold onto the changing aspects of reality as if they had a continuous existence that they are unsatisfactory for us. Emptiness is really just the same as interdependence or dependent origination, and some of the clearest accounts I've come across explain it in these terms. Thich Nhat Hanh's commentary on the Heart Sutra (which I recommend) describes it using his own terminology of 'inter-being'.
If you are a poet, you will see clearly that there is a cloud floating in this sheet of paper. Without a cloud, there will be no rain; without rain, the trees cannot grow; and without trees, we cannot make paper...So we can say that the cloud and the paper 'inter-are.' We cannot just be by ourselves alone; we have to inter-be with every other thing.
A class of Mahayana sutras called the Prajnaparamita (Perfection of Wisdom) sutras developed this concept of emptiness. The earliest is the Aṣṭasāhasrikā Prajñāpāramitā Sūtra or "Perfection of Wisdom in 8,000 Lines", which is chanted in a shortened form in Zen dojos as the Heart sutra. It includes a number of quite enigmatic lines on emptiness:
"Form is empty; emptiness is form. Emptiness is not other than form; form also is not other than emptiness. Likewise, feeling, discrimination, compositional factors and consciousness are empty."

"Shariputra, like this all phenomena are merely empty, having no characteristics. They are not produced and do not cease. They have no defilement and no separation from defilement. They have no decrease and no increase."
Emptiness is that which is beyond dualities - it is raw reality, prior to conceptualisation and language. It is not to be seen as another concept, set in opposition to phenomena such as form (matter), sensation, perception, mentality, or consciousness. Reality is not separate from appearance. Thich Nhat Hanh explains this beautifully as follows:
Form is the wave and emptiness is the water.
Probably the second most influential Buddhist thinker after Buddha himself was Nagarjuna who, at the time that Mahayana Buddhism was emerging, developed the concept of Sunyata with a thorough and extensive philosophy of negation - the best known exposition of his thought is the Mūlamadhyamakakārikā (Fundamental Verses on the Middle Way). Key features of this teaching are:
  • The Buddhist Concept of Emptiness of all things (i.e., all things, including the Buddha, have no inherent existence)
  • The identity of pratītyasamutpāda (Dependent Origination) with śunyatā
  • The indifferentiability of nirvāṇa from saṃsāra
  • The tentative or merely conventional nature of all truth
The former is expressed in terms of the 'emptiness of emptiness':
Whatever is dependently co-arisen
That is explained to be emptiness.
That, being a dependent designation,
Is itself the middle way.

Something that is not dependently arisen,
Such a thing does not exist.
Therefore a nonempty thing
Does not exist.
One of the problems with philosophies based (for teaching purposes) on negation, such as anatta, sunna and to an even greater extent the work of Middle Path philosophers such as Nagarjuna, is that it is easily interpreted as nihilism. Many people misinterpret these ideas as a denial of reality. But Nagarjuna's philosophy is not nihilistic, it is negative to avoid all attachment to concepts, all reification. But really it is indicating through denial and silence, that which is beyond language and concepts. It is intended to negate attachment to concepts in order to see through them to reality. He has prompted comparison with the (equally misunderstood) 20th century philosopher Ludwig Wittgenstein.

A group of Mahayana sutras referred to as the Tathagatagarbha (Buddha Womb) Sutras teach that there is a permanent, unchanging essence within each being. The term Tathagatagarbha can be variously translated as 'Buddha Womb', 'Buddha Embryo' etc, and is closely related to and sometimes synonymous with Buddha Nature. It may have arisen as a result of Hindu/Brahmanist influences since it arose during a Hindu revival in India. These sutras are in agreement that the Tathagatagarbha is an undefiled, eternal essence within all beings. It is presented as an antidote to a false, nihilistic understanding of emptiness. But, as I have already argued, to see these doctrines as nihilism is to totally (yet understandably) misunderstand them. A minority of Mahayana Buddhists adhere to this view literally. However such an interpretation seems essentially indistinguishable from the Vedic/Brahminist teachings of Atman that Buddhism rose out of and broke away from. Others see such interpretation as being in contradiction to the principles of anatman and sunyata. To me, this raises the question of why, if Buddha was essentially in agreement with the Brahminists, he felt any need to debate with them and to give radical, innovative teachings which directly contradicted them. Buddha rejected eternalism as well as annihilationism. How does this interpretation differ from eternalism? Is this not just another attempt to cling to atman, to imagined permanence? Another reification of concepts? How do we reconcile this with the rest of Buddhist philosophy?

Could it be that the authors of these sutras (which were of course attributed to Buddha, but which did not appear until several centuries after his death) had misunderstood such doctrines as Anatta, Sunyata and Madhyamaka philosophy as nihilism? Or perhaps they were creating an antidote to the popular misunderstanding of such teachings as nihilism - redressing the balance by teaching emptiness in positive terms.

In one of the Tathagatagarbha sutras, the Lankavatara Sutra, it is explained that the Tathagatagarbha doctrine is a teaching method:
Then Mahamati said to the Blessed One: In the Scriptures mention is made of the Womb of Tathágata-hood and it is taught that that which is born of it is by nature bright and pure, originally unspotted and endowed with the thirty-two marks of excellence. As it is described it is a precious gem but wrapped in a dirty garment soiled by greed, anger, folly and false-imagination. We are taught that this Buddha-nature immanent in everyone is eternal, unchanging, and auspicious. It is not this, which is born of the Womb of Tathágata-hood the same as the soul-substance that is taught by the philosophers? The Divine Atman as taught by them is also claimed to be eternal, inscrutable, unchanging, and imperishable. Is there, or is there not a difference?

The Blessed One replied: No, Mahamati, my Womb of Tathágata-hood is not the same as the Divine Atman as taught by the philosophers. What I teach is Tathágata-hood in the sense of Dharmakaya, Ultimate Oneness, Nirvana, emptiness, unborn-ness, unqualified ness, devoid of will-effort. The reason why I teach the doctrine of Tathágata-hood is to cause the ignorant and simple-minded to lay aside their fears as they listen to the teaching of ego-less-ness and come to understand the state of non-discrimination and imageless-ness. The religious teaching of the Tathágatas are just like a potter making various vessels by his own skill of hand with the aid of rod, water and thread, out of the one mass of clay, so the Tathágatas by their command of skillful means issuing from Noble Wisdom, by various terms, expressions, and symbols, preach the twofold ego-less-ness in order to remove the last trace of discrimination that is preventing disciples from attaining a self-realization of Noble Wisdom. The doctrine of the Tathágata-womb is disclosed in order to awaken philosophers from their clinging to the notion of a Divine Atman as transcendental personality, so that their minds that have become attached to the imaginary notion of "soul" as being something self-existent may be quickly awakened to a state of perfect enlightenment. All such notions as causation, succession, atoms, primary elements, that make up personality, personal soul, Supreme Spirit, Sovereign God, Creator, are all figments of the imagination and manifestations of mind. No, Mahamati, the Tathágata’s doctrine of the Womb of Tathágata-hood is not the same as the philosopher’s Atman.
Note the phrase 'the Tathágatas by their command of skillful means issuing from Noble Wisdom, by various terms, expressions, and symbols, preach the twofold ego-less-ness'. In what sense is the ego-less-ness twofold? I propose that it is twofold through both negative expression (anatta, sunyata) and positive expression (Tathagatagarbha, dependent origination).

In his article The Significance Of 'Tathagatagarbha' - A Positive Expression Of 'Sunyata' Heng-Ching Shih expresses the same argument in detail.
In this passage, the Buddha clearly identified the 'tathagatagarbha' with emptiness, markless, 'tathata', etc., meaning that the 'tathagatagarbha' is without any substantial entity. Then the question arises: -- if the 'tathagatagarbha' is empty by nature , why the Buddhas teach a 'tathagatagarbha' possessing all positive attributes, such as eternal (nitya), self ('atman'), bliss (sukha) and pure (subha)? ...It is pointed out in this passage that the 'tathagatagarbha' is empty in its nature yet real: it is 'Nirvana' itself, unborn, without predicates. It is where no false discrimination (nirvikalpa) takes place. There is nothing here for the Buddhas or Bodhisattvas to take hold of as an 'atman'. They have gone beyond the sphere of false discrimination and word. It is due to their wisdom and skillful means ('upaya') that they set up all kinds of names and phrases in order to save sentient beings from mistaken view of reality. In other words, it is exactly to help sentient beings case away their fear of 'anatman' that the 'tathagatagarbha' with positive attributes (i.e., 'asunya-tathagatagarbha') is taught, and at the same time it is to get rid of the clinging of 'atman' that the 'anatman-tathagatagarbha' is taught. Thus it is clear that the 'tathagatagarbha' is not an Upanishadic 'atman'.
There is a passage in the 'Mahaparinirana Sutra' in which Buddha nature is defined as the ultimate emptiness and the Middle Way. It reads:
Good son, Buddha nature is the ultimate emptiness ,which is 'prajna' itself. [False] emptiness means not to perceive emptiness or non-emptiness. The wise perceive emptiness and non-emptiness, permanence and impermanence, suffering and happiness, self and non-self. What is empty is 'samsara' and what is not empty is great 'nirvana' ... Perceiving the non-self but not the self is not the Middle Way. The Middle Way is Buddha nature.
Heng-Ching Shih explains this as follows:
The essential point of this passage is that true emptiness, or in this case Buddha nature, trancends any dictomony [between] being and non-being, self and non-self, suffering and happiness, etc. Ordinary people and the heterodox see only the existence of self, while 'Sravakas' and Pratyekabuddhas perceive only the non-self, but not the existence of a self. Clinging to one extreme or the other, they cannot realize the ultimate, and true emptiness and consequently cannot realize the Middle Way. Without the Middle Way, they are not able to comprehend Buddha nature. Trying to lessen the monistic flavour of the Buddha nature, the 'Mahaparinirvana Sutra' interprets Buddha nature as both encompassing and transcending the notions of self and non-self. It makes the doctrine of the Buddha nature adhere closely to the Buddhist teaching of non-duality and the Middle Way. Thus Buddha nature should not be treated as equivalent to the monistic absolute. If it does seemly indicate the presence of a substantive self, it is actually a positive expression of emptiness.
Interpreting the Tathagatagarbha doctrine as soteriological - as a teaching device - rather than as theoretical and literal in this way, we can resolve an apparent conflict into a teaching which is harmonious with the rest of Buddhist philosophy.

As with Thich Nhat Hanh's teaching of emptiness, we have another, relatively easy to understand, positive expression of the core teaching of Buddhism. And again we have the danger of literalism and reification - an even greater danger in this case due to the ambiguity of the texts and the ease with which they can be seen as metaphysics. The key, I believe, is to see all of these teachings as just that - to walk a Middle Path, avoiding literalism, clinging to no particular articulation, positive or negative, but instead letting go of all attachment to concepts and language and instead being open to reality itself without such 'mediation'. All good Buddhist teachings are knowingly pragmatic and soteriological, in my opinion.

Rebirth, Reassessed


The rise of Buddhism in the west is undoubtedly linked with it's relative compatability with the dominant rational, empirical and pragmatic worldview. The single biggest obstacle to practice for westerners is probably the belief in rebirth and karma, since this this is not part of our worldview, nor does there seem to be any rational or empirical justification for accepting this. The majority of Buddhist orders would insist on acceptance of this doctrine in order to be a serious practitioner, certainly for one to become a monk. It was a barrier for me when I first encountered Buddhism as an undergraduate. And it remains an issue for many. It was probably reading Stephen Batchelor's book Buddhism Without Beliefs, in which the author argues for the validity of agnosticism on such matters, that allowed me to see a route forward and I'm grateful to him for that. I've not read any more recent writings, however, I got the impression that he was still wrestling with these issues.

Why do most traditional Buddhists believe in traditional rebirth and karma?
For most Buddhists, these concepts are part of the worldview in which they are raised. Believing these things are as natural as the understanding that the earth rotates around the sun is for a modern westerner. There are several arguments sometimes made in Buddhism for accepting these notions, but none I have personally come across hold much water.

  1. Buddha taught them to be true.
    Even assuming (not unreasonably) that the sutras have reliably passed down what the Buddha taught, this argument doesn't stand up. First, this would only be justification if the Buddha was literally omniscient and there is no good reason to suppose this. Interestingly, the believer himself would have to be omniscient as well in order to know for certain that the Buddha was omniscient. Secondly, the Buddha made several statements indicating that his teachings were merely a vehicle for passing across to nirvana, thus there is room for the possibility that they were metaphors using common concepts of the time to indicate something more difficult to articulate (such as the realisation that we don't exist as separate continuous entities in the first place).


  2. Buddha was right about suffering so we should have faith in the rest
    This is the argument I've seen given by Bhikkhu Bodhi on this subject. Initially we may have no belief in traditional rebirth and karma, but as we begin to see the fruits of our practice, we increasingly trust the Buddha not just on the matter of the elimination of suffering, but on matters which we cannot experience ourselves such as rebirth and karma. This is an example of the logical fallacy known as the Appeal to Authority. Someone's expertise on one subject does not make him or her an authority on other matters. What is important is whether a particular claim can be validated or not.

  3. We can experience this ourselves in meditation or upon enlightenment
    Well until this can actually be verified with experience, this comes back to blind faith again. Even if we did have experiences during meditation or special states, they might be the product of imagination - it isn't difficult to produce vivid experiences or false memories during states of deep mental relaxation.
Did Buddha believe in rebirth and Karma?
It might be tempting for those who practice the dharma and yet who do not believe in these ideas - especially under pressure from traditionalistic Buddhists who accuse them of being 'not real Buddhists' - to attempt to bolster their position, by arguing either that the Buddha did not really teach rebirth and karma or that his teachings were just metaphors. From my (far from complete) readings of the Pali Canon it seems very clear that he did teach literal rebirth and karma and went into details of their mechanics at times. It would be incredible for these central ideas to have been levered into position at a later time. Nor have I found any direct evidence that those specific teachings were intended merely as metaphorical devices. But certainly there are several examples of him indicating that much or all of his teachings were just teaching devices, vehicles.

Why did Buddha believe or at least teach karma and rebirth?
The Buddha was born into a culture in which the concepts of karma and rebirth were commonplace in religious thought. The Buddha did not spontaneously produce these ideas from nowhere. Karma originated with Jainism and rebirth is a modified form of reincarnation which comes from Vedic thought. Denial of these concepts was associated with nihilism or materialism.

Why don't I believe in rebirth and karma?
First of all, it's not accurate to say that I don't believe in rebirth and karma. More precisely, those beliefs I provisionally have about rebirth and karma are not exactly the same as those which Siddhartha Gautama seems to have taught.

Karma is volitional activity and the consequences, good or bad, of that activity. Everyday human experience reveals the reality of this and increasing awareness and compassion allows us to create better consequences. Every moment we send out chaotic ripples of change across the universe, the vast majority of which have consequences we have no control over. This doesn't mean, however, that I have any reason or evidence to believe that all actions which are conventionally regarded as 'bad' always lead to increased suffering for the perpetrator. Nor is there any good justification for supposing that consequences inevitably revisit 'the same person' reborn.

All the evidence available from both science and introspection suggest that there is no continuous self which survives intact or unchanged even from one moment to the next. Instead we have continuously changing psychological processes, including the processes which produce that very sense of continuity. Yet this sense of self reappears again and again. This is sometimes called 'moment to moment rebirth'. On the other hand, I can find no justification for believing that at death, the causal chain of my being is somehow (and for some unexplained reason) focussed through 12 links of dependent arising onto the formation of a single future being.

For me, the traditional teachings of rebirth and karma are like fingers pointing to the interconnectedness of everything, to emptiness, presented from within the context of the Vedic worldview. Emptiness itself is is universal, particular theories about life after death are culturally dependent and impermanent.

The translation I have (Bhikku Bodhi) of the Pali Canon implies that Buddha did not spontaneously recall his previous lives, but that, during a profound state of meditation on the night of his awakening, he deliberately turned his attention to recall them. This implies that he already had a belief in them gained from his cultural environment. From my understanding of psychology and my personal experiences of self-hypnosis and visualisation I know that such apparent memories under such circumstances do not constitute at all reliable evidence for past lives.

In the Kalama Sutta, Buddha himself says that one need not believe in rebirth and karma in order to be a successful practitioner.

Karma Police
One of the appealing things about Zen is that belief in doctrines isn't given much importance, but when I took the Boddhisattva vows I had an interview with Master Taiun to ensure I wasn't taking the vows on a false understanding. The answers he gave me were reassuring.

Nevertheless some Buddhists are less open and less tolerant. The administration on the eSangha Buddhist discussion board hold the opinion that since Zen is a school of Buddhism they have to accept the fundamentals and that those fundamentals include traditional karma and rebirth. I wrote about my own experiences of this on my personal blog. Jundo James Cohen, a Zen priest, was recently banned from the same board apparently for saying that...

...traditional ideas of rebirth and reincarnation are not to be taken literally in
this modern age; and (2) Shakyamuni Buddha was a man, not a god or super-human
being, and though enlightened … was a human being like the rest of us.
and

But, in fact, the non-literalist views I am expressing on Reincarnation
represent, I believe, the generally dominant view among Zen teachers in the West
right now. The reason is not that we have lost the direct line to Buddha’s brain
that you’all so evidently possess. The reason is, quite simply, that we no
longer live in an age of superstition and hocus-pocus. I do not believe in a
magical view of Reincarnation for much the same reason that I do not believe in
flying dragons, the tooth fairy, genies, Qilin (a kind a giraffe with fish
scales and wings) and such. We do not believe that earthquakes are caused by
giant catfish under the earth, or that stomach aches are due to ghost
possession, and other things that the same primitive folks (who wrote the
Sutras) believed in. Now, we know a little better (although, granted, we have
our own modern myths and superstitions).
Such people want to claim that Buddha is omniscient and infallible and that anyone who disagrees is a heretic. Rather than admit that Zen does not require adherence to such dogma, they intimidate or ban the individual who states such a perspective.

No-Self and Tony Soprano
I don't generally talk to my work colleagues about Buddhism, but a few of them know that I practice and one of the guys in the team is a Mormon, and he brings up the subject of religion sometimes. So one day he was explaining his beliefs about the after life and he asked me if I believed in reincarnation and I went into an explanation that most Buddhists believe in rebirth which is a chain of cause and effect rather than the continuation of a self or soul. And blah, blah, blah. But later I found a better way of expressing this.

My partner and I are working our way through the Sopranos on DVD - I can't recommend it enough by the way - and we were watching an episode in which Tony Soprano was convalescing in hospital after being shot. One of the other guys chatting in the room was a scientist who came out with a great description of the non-existence of separate entities, which I felt described the Buddhist perspective in a contemporary and rational way, far better than most of the stale descriptions of rebirth and karmic dogma given by Buddhists. Next time I get asked the 'reincarnation' question, I'll answer along the same lines (and yes, I do think that non-practitioners can realise emptiness, to at least some extent - this is because reality is inherently empty, it's emptiness is not something which has to be passed down in the form as dogma.)

Pauli (one of Tony's most senior men): Look at you T. You do your uncle a kindness, you get shot for your efforts. You think you got family, but in the end they fuck you too.
Tony Soprano : [to the others in the room] He's grieving. His aunt just died.
Pauli: Each and every one of us, we're alone in the ring, fighting for our lives. Just like that poor prick. [referring to a boxer on the TV]
John Schwinn, a scientist: That's one way to look at it
Tony: You got a better one? ...
John Schwinn: Well, it's actually an illusion that those boxers are separate entities....Their separate entities is simply the way we choose to perceive them.
Tony: I didn't choose nothin.
John Schwinn: It's physics. Schrodinger's equation. The boxers, you, me - we're all part of the same quantum field...Think of the two boxers as ocean waves or currents of air - two tornadoes. They appear to be two separate things, but they're not. Tornadoes are just the wind stirred up in different directions. The fact is, nothing is separate - everything is connected ...
Tony: Get the fuck outta here
John Schwinn: The universe is just one big soup of molecules bumping up against one another. The shapes we see exist only in our own consciousness...
Pauli: You're so fucking smart, fix that TV.
John Schwinn: [Laughs] OK
