Here's something I found on another forum, thought of sharing
it:
DHARMA TALK ON ONE MIND
by Bassui Tokusho Zenji
If you would free yourself of the sufferings of the Six Realms, you
must learn the direct way to become a Buddha. This way is no other
than the realization of your own Mind. Now what is this Mind? It is
the true nature of all sentient beings, that which existed before
our parents were born and hence before our own birth, and which
presently exists, unchangeable and eternal. So it is called one's
Face before one's parents were born. This Mind is intrinsically
pure. When we are born it is not newly created, and when we die it
does not perish. It has no distinction of male or female, not has
it any coloration of good or bad. It cannot be compared with
anything, so it is called Buddha-nature. Yet countless thoughts
issue from this Self-nature as waves arise in the ocean or as
images are reflected in a mirror.
If you want to realize your own Mind, you must first of all look
into the source from which thoughts flow. Sleeping and working,
standing and sitting, profoundly ask yourself, "What is my own
Mind?" with an intense yearning to resolve this question. This is
called "training" or "practice" or "desire for truth" or "thirst
for realization." What is termed Zazen is no more than looking into
one's own mind. It is better to search your own mind devotedly than
to read and recite innumerable sutras and dharani every day for
countless years. Such endeavors, which are but formalities, produce
some merit, but this merit expires and again you must experience
the suffering of the Three Evil Paths. Because searching one's own
mind leads ultimately to enlightenment, this practice is a
prerequisite to becoming a Buddha. No matter whether you have
committed either the ten evil deeds or the five deadly sins, still
if you turn back your mind and enlighten yourself, you are a Buddha
instantly. But do not commit sins and expect to be saved by
enlightenment [from the effects of your own actions. Neither
enlightenment] nor a Buddha nor a Patriarch can save a person who,
deluding himself, goes down evil ways.
Imagine a child sleeping next to its parents and dreaming it is
being beaten or is painfully sick. The parents cannot help the
child no matter how much it suffers, for no one can enter the
dreaming mind of another. If the child could awaken itself, it
could be freed of this suffering automatically. In the same way,
one who realizes that his own Mind is Buddha frees himself
instantly from the sufferings arising from [ignorance of the law
of] ceaseless change of birth-and-death. If a Buddha could prevent
it, do you think he would allow even one sentient being to fall
into hell? Without Self-Realization one cannot understand such
things as these.
What kind of master is it that this very moment sees colors with
the eyes and hears voices with the ears, that now raises the hands
and moves the feet? We know these are functions of our own mind,
but no one knows precisely how they are performed. It may be
asserted that behind these actions there is no entity, yet it is
obvious they are being performed spontaneously. Conversely, it may
be maintained that these are the acts of some entity; still the
entity is invisible. If one regards this question as unfathomable,
all attempts to reason [out an answer] will cease and one will be
at a loss to know what to do. In this propitious state deepen and
deepen the yearning, tirelessly, to the extreme. When the profound
questioning penetrates to the very bottom, and that bottom is
broken open, not the slightest doubt will remain that your own Mind
is itself Buddha, the Void-universe. There will then be no anxiety
about life or death, no truth to search for.
In a dream you may stray and lose your way home. You ask someone to
show you how to return or you pray to God or Buddhas to help you,
but still you can't get home. Once you rouse yourself from your
dream-state, however, you find that you are in your own bed and
realize that the only way you could have gotten home was to awaken
yourself. This (kind of spiritual awakening] is called "return to
the origin" or "rebirth in paradise." It is the kind of inner
realization that can be achieved with some training. Virtually all
who like Zazen and make an effort in practice, be they laymen or
monks, can experience to this degree. But even such [partial]
awakening cannot be attained except through the practice of Zazen.
You would be making a serious error, however, were you to assume
that this was true enlightenment in which there is no doubt about
the nature of reality. You would be like a man who having found
copper gives up the desire for gold.
Upon such realization question yourself even more intensely in this
wise: "My body is like a phantom, like bubbles on a stream. My
mind, looking into itself, is as formless as empty-space, yet
somewhere within sounds are perceived. Who is hearing?" Should you
question yourself in this wise with profound absorption, never
slackening the intensity of your effort, your rational mind
eventually will exhaust itself and only questioning at the deepest
level will remain. Finally you will lose awareness of your own
body. Your long-held conceptions and notions will perish, after
absolute questioning, in the way that every drop of water vanishes
from a tub broken open at the bottom, and perfect enlightenment
will follow like flowers suddenly blooming on withered trees.
With such realization you achieve true emancipation. But even now
repeatedly cast off what has been realized, turning back to the
subject that realizes, that is, to the root bottom, and resolutely
go on. Your Self-nature will then grow brighter and more
transparent as your delusive feelings perish, like a gem gaining
luster under repeated polishing, until at last it positively
illumines the entire universe. Don't doubt this! Should your
yearning be too weak to lead you to this state in your present
lifetime, you will undoubtedly gain Self-realization easily in the
next, provided you are still engaged in this questioning at death,
just as yesterday's work half done was finished easily today.
While you are doing Zazen neither despise nor cherish the thoughts
that arise; only search your own mind, the very source of these
thoughts. You must understand that anything appearing in your
consciousness or seen by your eyes is an illusion, of no enduring
reality. Hence you should neither fear nor be fascinated by such
phenomena. If you keep your mind as empty as space, unstained by
extraneous matters, no evil spirits can disturb you even on your
deathbed. While engaged in Zazen, however, keep none of this
counsel in mind. You must only become the question "What is this
Mind?" or "What is it that hears these sounds?" When you realize
this Mind you will know that it is the very source of all Buddhas
and sentient beings. The Bodhisattva Kannon is so called because he
attained enlightenment by perceiving -i.e., grasping the source of
the sounds of the world about him.
At work, at rest, never stop trying to realize who it is that
hears. Even though your questioning becomes almost unconscious, you
won't find the one who hears, and all your efforts will come to
naught. Yet sounds can be heard, so question yourself to an even
profounder level. At last every vestige of self-awareness will
disappear and you will feel like a cloudless sky. Within yourself
you will find no "I," nor will you discover anyone who hears. This
Mind is like the void, yet it hasn't a single spot that can be
called empty. This state is often mistaken for Self-realization.
But continue to ask yourself even more intensely, "Now who is it
that hears?" If you bore and bore into this question, oblivious to
anything else; even this feeling of voidness will vanish and you
will be unaware of anything-total darkness will prevail. [Don't
stop here, but] keep asking with all your strength, "What is it
that hears?" Only when you have completely exhausted the
questioning will the question burst; now you will feel like a man
come back from the dead. This is true realization. You will see the
Buddhas of all the universes face to face and the Patriarchs past
and present. Test yourself with this koan: "A monk asked Joshu:
'What is the meaning of Bodhidharma's coming to China?' Joshu
replied: 'The oak tree in the garden.' " Should this koan leave you
with the slightest doubt, you need to resume questioning, "What is
it that hears?"
If you don't come to realization in this present life, when will
you? Once you have died you won't be able to avoid a long period of
suffering in the Three Evil Paths. What is obstructing realization?
Nothing but your own half-hearted desire for truth. Think of this
and exert yourself to the utmost.
