Zen
Buddhism (which is known as Chan in China, where it originated; Son in
Korea; and Thien in Vietnam, and is based on the Sanskrit word dhyana, which is usually translated as "absorption" in modern English, but sometimes simply as "meditation"),
according to its practitioners, is, as famous proponent of Zen Buddhism Masao Abe translates it,
"[a]n independent transmission outside the teaching
of the scriptures, [d]irectly pointing to man's
Mind, [a]wakening of one's (Original-) Nature, thereby
actualizing one's own Buddhahood" (attributed to
Bodhidharma, founder of the Chan/Zen tradition, who is depicted as the
transmitter of this tradition from India to China, and not its founder,
in traditional Zen accounts). However, like all traditions Zen Buddhism has
a history. It is not an ahistorical
essence or a “wafting cloud in the sky” (D.T. Suzuki, An Introduction to Zen Buddhism, p. 41), at least not in
practice.
Zen Buddhism has definitive practices: zazen or seated meditation, of which
there are several kinds (see The Three Pillars of Zen by Philip Kapleau Roshi, pp. 31-44, 141-142), and contemplation of koans, or non-logical statements designed to snap the mind out of
its ordinary modes of cognition, at least after several years of intense
practice, including some preliminary training in seated meditation. It even has formal rituals, such as the
chanting of sutras and the performance of funerals by Zen Buddhist monks (see The Other Side of Zen by Duncan Ryuken Williams and Soto Zen in Medieval Japan by William Bodiford for information on how such aspects of Zen Buddhism developed in Medieval Japan).
Zen Buddhism has a rigid code of discipline (more rigid
than most other forms of monastic Buddhism, in fact - see The Zen Monastic Experience by Robert Buswell and The Empty Mirror
by Janwillem van de Wetering for Western accounts of contemporary Zen
monasticism, the former in Korea and the latter in Japan; see The Baizhang Zen Monastic Regulations for a sample of some of the rules and regulations that Zen monks have historically been expected to follow). It is very hierarchical and very traditional, as the mind of awakening has allegedly been passed from master to disciple
for many generations, and respect for and obedience to one’s master is still
expected in East Asian Chan/Son/Zen/Thien training. (I will note
here that there is one feature of Zen Buddhism that has been
over-emphasized by those who see Zen as an exotic, foreign practice, and
under-emphasized by those with a mere philosophical interest in Zen
Buddhism: the use, by Zen masters, of the keisaku or kyosaku, or a stick used to hit disciples in order to help rouse them to awakening. I will not go into details about this here.)
Still, the goals of Zen Buddhism are
quite similar to those of Philosophical Daoism. The primary goal of practitioners of Zen Buddhism is to transcend all limitations and dualities, including oneness
or any concept of oneness (which is dualistic because it is exclusive of
diversity or many-ness). In principle,
it is amoral, and only considers morality valuable if it aids one in practicing
meditation and the other traditional practices of Zen.
At the same time, it really is part of
Buddhism, so it also (again, in principle) accepts the traditional cosmology of
Buddhism, including its idea of continuous rebirth in the six realms of
existence until awakening or buddhahood is realized. That Zen Buddhists have historically been more
likely to interpret these teachings nonliterally than other Buddhists (again,
“more likely” – many, and probably even most Chan and Zen Buddhists
historically interpreted these teachings literally, but that has changed in the
last century, as it has for many “modernist” Buddhists in Asia and the West)
does not negate the fact that they have been present in Zen Buddhism, as they
are present in some of the Mahayana sutras upon which Zen Buddhism is
based, such as the Lankavatara Sutra.
In addition, Zen Buddhism is a Mahayana
tradition, meaning it regards the bodhisattva, or the one who aspires to full
buddhahood out of compassion for all sentient beings (the basis of this
aspiration is known as bodhicitta, or
the mind of awakening), as the ideal which all sentient beings should
seek. (Heinrich Dumoulin, a Catholic priest, made this point most forcefully in his book Zen Buddhism: A History, India & China (Volume 1) - not to be confused with Dumoulin's earlier edition of this work called A History of Zen Buddhism,
which has Catholic triumphalist claims that are utterly inappropriate
in a scholarly work on the history of a religion, even if they would not
be objectionable in an apologetic work - fortunately, Dumoulin changed
his approach for later editions.)
Zen Buddhism excels
in its methodology. Zazen, especially the form of it known as shikantaza (which is the practice of “just sitting” with the mind
both fully alert and relaxed, without the aid of counting the breath or any
other “crutch,” and is extremely difficult - Kapleau's Three Pillars of Zen, pp. 60-62, provides an excellent description of this practice), for those capable of it, as well
as contemplation of a koan, are very
effective means (at least for those who rigorously practice them for many
years) for freeing the mind from its habitual tendency to set up dualities
between likes and dislikes, and thus awakening a person to his or her original
nature.
To clarify, real Zen has the
power to do this. Armchair Zen, or the practice of sitting around discussing the “Zen
of” every topic under the sun, or of identifying states of great joy or even
occasional feelings of oneness with nature with Zen, while perhaps warranting
nothing more than a light smile (and certainly not any kind of self-righteous
condemnation), does not have the power to liberate the mind from all dualities,
or, more accurately, to introduce a person to his or her original nature, to
who he or she has always been but has not recognized before due to attachment
to various likes and dislikes. One does
not need to remove these attachments; rather one only needs to recognize
the
buddha-nature of the mind, and upon the realization of this, likes and
dislikes, which are lacking in any intrinsic existence or essential
nature,
will vanish of their own accord. Still, it is better, at all stages of
practice, to have as few attachments as possible, which I suspect is the
rationale for the strict discipline of Zen monasteries historically.
The principal goal
of Zen Buddhism, and specifically of the practice of zazen, is the realization or recognition of one’s true nature, of
seeing into one’s mind and recognizing that one has always been a buddha, though one has
not realized it before. This is
awakening or bodhi (the most complete
form of which is known as anuttara-samyak-sambodhi),
and it is known in Japanese as kensho
or satori (the latter being a
“deeper” realization of one’s buddha-nature than the former - see The Three Pillars of Zen, p. 409).
The goal of Zen Buddhism is not just to
experience kensho or satori once, but to constantly remain in
that state no matter what other activities one engages in on a daily
basis (The Three Pillars of Zen, pp. 53-56). This actualization of one’s
intrinsic buddhahood in all situations is known in Japanese as mujodo no taigen (Ibid.). As an initial matter, the Zen Buddhist disciple
must learn to concentrate the mind one-pointedly (this is called joriki in Japanese), keeping out all external
distractions or attachments (Ibid.). This type
of concentration takes time to learn for almost all people, but it is just the first step
in the process of awakening. Although
awakening occurs “instantaneously” when it happens, it takes several years of
training before most people get to the point where they can actually have this
“instantaneous” experience of awakening.
On the negative side, Zen Buddhism has a tendency
to become excessively anti-intellectual, much as many other traditions (such as
Advaita Vedanta) have a tendency to become overly-intellectual. Unfortunately, it often happens that Zen
Buddhists teach metaphysical doctrines, whether explicitly or implicitly, but
immediately criticize others those who rationally examine or proclaim
metaphysical doctrines (many of those who claim to follow the Advaitin sage
Ramana Maharshi do the same thing). The problematic nature of this situation can best be addressed by accepting that on one level (let us call it that of the seeker, or one who is uncertain about the nature and goal of existence and is looking for answers) it is appropriate to analyze and evaluate any teachings, including the teachings of Zen Buddhism, to determine consistency, sensibility, and practicality, while on another level (let us call it that of the practitioner, or one who is committed to a particular tradition based on what he or she believes to be the certain, probable, or even possible nature and goal of existence), it is best, to put it bluntly, to shut up and practice what the tradition teaches so that one can make some real progress.
This, of course, applies to all traditions, not just Zen Buddhism, but it seems particularly relevant to Zen Buddhism, since Zen (the “Buddhism” part is often dropped from its name in Western discourse, even though in its origins and in East Asia to this day it is plainly and explicitly a Buddhist tradition) is usually understood in the Modern West as D.T. Suzuki’s “wafting cloud,” that is, as beyond all concepts and speculation, and possible for any person to realize immediately, in the here and now, without years of dedicated practice under a qualified Zen Buddhist master. (Of course, in theory Zen Buddhism teaches and has historically taught that it is possible to realize one’s true nature, to instantly recognize one’s intrinsic buddhahood at any time, but in practice very few people have ever realized their intrinsic buddhahood without first engaging in years of dedicated practice in zazen, the contemplation of koans, or both.)
RECOMMENDED READING:
The Three Pillars of Zen, by Philip Kapleau Roshi. This is easily the best book on Zen Buddhism in the English language, as famous scholar of religion Huston Smith claimed. I recommend it for those who wish to practice Zen Buddhism. It gives some historical information about Zen Buddhism, but its emphasis is on the actual practice of Zen Buddhism.
Zen Buddhism: A History, Volume 1 and Zen Buddhism: A History, Volume 2, by Heinrich Dumoulin. These books describe Zen Buddhism and its historical development in the context of Mahayana Buddhism and the discourses (or sutras) that the Mahayana attributes to the historical Buddha, Siddhartha Gautama or Shakyamuni. The first edition, A History of Zen Buddhism, is less a scholarly work than a work of Catholic triumphalism, so is not the best resource for those who wish to learn about Zen Buddhism.
Dogen's Manuals of Zen Meditation, by Zen Master Dogen, translated by Carl Bielefeldt. These are comprehensive manuals of meditation by perhaps Zen Buddhism's greatest master, Dogen. Most Zen masters have held that one should study under a living master, but these are probably the best instructions on meditation or anybody who wants to try to practice on their own (which is very difficult to do).
Shobogenzo, by Zen Master Dogen. This is a very advanced philosophical and theoretical text by arguably the greatest Zen master, Dogen. It is for very serious students of Buddhism or comparative philosophy.
Platform Sutra of the Sixth Patriarch, translated by Red Pine. This is probably the greatest theoretical introduction to Zen Buddhism, and it explains almost all of the theoretical foundations of the varieties of Zen Buddhism that have flourished in East Asia for over a thousand years.
Manual of Zen Buddhism, with works translated by D.T. Suzuki. This is Suzuki's greatest book, since it translates many of the texts that are and have long been central to Zen Buddhism. Here, Zen Buddhism is not presented as a "wafting cloud in the sky," but as a tradition with a history, including texts it regards as significant.
Zen and Western Thought, by Masao Abe. I find Masao Abe's philosophical musings on Zen Buddhism, and his comparisons between Zen Buddhism and Western Philosophy, to be thought-provoking, but this is not the best place to start in learning about the practice, theory, or history of Zen Buddhism.
An Introduction to Zen Buddhism and Essays in Zen Buddhism by D.T. Suzuki. In my opinion, the works of D.T. Suzuki are not a good place to start in learning about Zen Buddhism, especially not the practice or the history thereof. Nonetheless, his works are philosophically engaging at times, and need not be dismissed wholesale.
