Yesterday I was reading an article on meditation and it quoted something from Master Nan Huai Chin which I thought was pretty good.
The First Issue
The first issue has to do with the sixth patriarch's enlightenment, clarifying the mind and seeing its essential nature, along with two expressions in Shen-hsiu's verse. In the Altar Sutra of the Sixth Patriarch, which has come down through history in several different versions, as well as in the records of the various texts of the Zen school, there are stories about the sixth patriarch's first enlightenment that are not very much different from one another. In Chinese Zen, beginning with the fifth patriarch Hungjen, people were instructed to recite the Diamond Prajnaparamita sutra as a means of entering the Way, thus changing Great Master Bodhidharma's didactic method of using the Lankavatara sutra to seal the mind. This can only be called a change in the method of instruction; there is no difference at all in the essential message of Zen. The main import of the Diamond sutra is to clarify the mind and see its essential nature. Here and there it explains the truth of essential emptiness as realized by prajna. The method of cultivating practice to seek realization therein emphasizes the three words ''skillfully guarding mindfulness." It explains the real character of essential emptiness, saying, "the past mind cannot be apprehended, the future mind cannot be apprehended, the present mind cannot be apprehended." The goal is perfect knowledge of "enlivening the mind without dwelling on anything."
For the sake of obtaining a general understanding of the Zen principle of governing the mind, I will presently use modern concepts to make a comparatively easy and lucid explanation. This can also serve as an instructional basis for cultivating practice, because it is a simple and swift method of cultivating mind and nurturing its essential nature.
Step One:
First we have to quietly and calmly observe and examine our own inner consciousness and thoughts, and then make a simple analysis in two parts. The first part consists of the thoughts and ideas produced from sensory feelings like pain, pleasure, fullness and warmth, hunger, cold, and so on. All of these belong to the domain of sensory awareness; from them are derived activities of cognitive awareness, such as association and imagination. The other part consists of consciousness and thought produced by cognitive awareness, such as vague emotions, anxieties, anguish, discriminating thoughts regarding people, oneself, and inner or outer phenomena, and so on. Of course the latter part also includes intellectual and scholastic thinking, as well as the very capacity one has to observe one's own psychological functions.
Step Two:
The next step comes when you have arrived at the point where you are well able to understand the activity of your own psychological functions. Whether they be in the domain of sensory awareness or in the domain of cognitive awareness, they are each referred to generally as a single thought: when you can reach the point where in the interval of each thought you can clearly observe each idea or thought that occurs to your mind, without any further absentmindedness, awareness, or vagueness, then you can process them into three levels of observation.
Generally speaking, the preceding thought (thinking consciousness) that has just passed is called the past mind, or the prior thought; the succeeding thought (thinking consciousness) that has just arrived is called the present mind, or the immediate thought; while that which has yet to come is of course the future mind, or the latter thought. However, since the latter thought has not yet come, you do not concern yourself with it. But you must not forget that when you take note that the latter thought has not yet come, this itself is the present immediate thought; and the moment you realize it is present, it has at once already become past.
Step Three:
Now the next step is when you have practiced this inner observation successfully for a long time. You watch the past mind, present mind, and future mind with lucid clarity and then develop familiarity with the state of mind of the immediate present, when the past mind of the former thought has not yet come. This state of mind in the instant of the immediate present then should subtly and gradually present an open blankness.
But this open blankness is not stupor, lightheadedness, or like the state before death. It is an open awareness that is lucid and clear, numinous and luminous. This is what the Zen masters of the Sung and Ming dynasties used to call the time of radiant awareness.
If you really arrive at this state, you will then feel that your own consciousness and thinking, whether in the domain of sensory awareness or in the domain of cognitive awareness, are all like reflections on flowing water, like geese going through the endless sky, like the breeze coming over the surface of water, like flying swans over the now: no tracks or traces can be found. Then you will finally realize that everything you think and do in everyday life is all nothing more than floating dust or reflections of light; there is fundamentally no way to grasp it, fundamentally no basis to rely upon. Then you will attain experiential understanding of the psychological state in which “the past mind cannot be apprehended, the future mind cannot be apprehended, the present mind cannot be apprehended.”
Step Four:
Next after that, if you really understand the ungraspability of the past, present, and future mind and thought, when you look into yourself it will turn into a laugh.
By this means you will recognize that everything and every activity in this mind is all the ordinary person disturbing himself. From here, take another step further to examine and break through the pressure produced by biological sensation and physical action and movement stimulated by thought, seeing it all as like bubbles, flecks of foam, or flowers in the sky. Even when you are not deliberately practicing self-examination, on the surface it seems like all of this is a linear continuity of activity; in reality what we call our activity is just like an electric current, like a wheel of fire, like flowing water: it only constitutes a single linear continuity by virtue of the connecting of countless successive thoughts. Ultimately there is no real thing at all therein. Therefore you will naturally come to feel that mountains are not mountains, rivers are not rivers, the body is not the body, the mind is not the mind. Every bit of all of this is just a dreamlike floating and sinking in the world, that is all. Thus you will spontaneously understand “enlivening the mind without dwelling on anything.” In reality, this is already the subtle function of “arousing the mind fundamentally having no place of abode.”
Step Five:
Next, after you can maintain this state where you have clarified the consciousness and thinking in your mind, you should preserve this radiant, numinous awareness all the time, whether in the midst of stillness or in the midst of activity, maintaining it like a clear sky extending thousands of miles, not keeping any obscuring phenomena in your mind. Then when you have fully experienced this, you will finally be able to understand the truth of human life, and find a state of peace that is a true refuge. But you should not take this condition to be the clarification of mind and perception of essential nature to which Zen refers! And you should not take this to be the enlightenment to which Zen refers! The reason for this is because at this time there exists the function of radiant awareness, and you still don't know its comings and goings, and where it arises. This time is precisely what Han-shan, the great Ming dynasty master, meant when he said, “It is easy to set foot in a forest of thorns; it is hard to turn around at the window screen shining in the moonlight.”
-------------------------------
In all of what I have said here, I have provisionally used a relatively modern method of explaining the conditions of human psychological activities and states. At the same time I have used this to explain what transpired when the sixth patriarch of Zen experienced an awakening on hearing someone recite the line of the Diamond sutra which says, "Enliven the mind without dwelling on anything." If through this you can understand the process of inner work and mental realization represented by the verse composed by the sixth patriarch's senior colleague Shen-hsiu, "The body is the tree of enlightenment, the mind is like a bright mirror stand; wipe it off diligently time and again, not letting it gather dust," then you can thereby know the sixth patriarch's realm of mental realization as represented by his verse, "Enlightenment basically has no tree, and the bright mirror has no stand; originally there is not a single thing, so where can dust gather?" If you make a comparison between these two, you will naturally be able to understand why the fifth patriarch Hung-jen summoned the sixth patriarch to his room in the third watch of the night and entrusted him with the robe and bowl.
However, "Originally there is not a single thing, so where can dust gather," still represents his attainment before he received the transmission of the robe and bowl. Don't forget the states mentioned above, because the state of "originally there is not a single thing" is like the realm of apricot blossoms in the snowy moonlight, which although clear and refined, is after all only one side of the matter, the silent cold of empty silence devoid of any living potential. The time the sixth patriarch made a complete breakthrough to great enlightenment was when he went into the fifth patriarch's room in the third watch of the night, and the fifth patriarch questioned him closely about "enlivening the mind without dwelling on anything," forcing him to go a step further to understand thoroughly the ultimate basis of the essential nature of mind. That is why he said, "Who would have expected that intrinsic nature is fundamentally pure of itself? Who would have expected that intrinsic nature is fundamentally unborn and unperishing? Who would have expected that intrinsic nature is fundamentally complete in itself? Who would have expected that intrinsic nature is fundamentally immovable? Who would have expected that intrinsic nature can produce myriad phenomena?" This finally represents the realm of immediacy and enlightenment in the "sudden enlightenment at a word'' spoken of in Zen.
But it will not do to forget how the sixth patriarch lived in hiding among a group of hunters after that, spending fifteen years at sustained cultivation after his enlightenment. By this it can be understood how the Lankavatara sutra brings up both the sudden and the gradual, and Zen includes both the sudden and the gradual. As it is said in the Surangama sutra, "The principle is to be understood all at once; then, using this understanding to clear them up, phenomena are to be worked on gradually, exhausted through a step-by-step process." This indicates the equal importance of sudden and gradual. Nowadays people who talk about Zen studies cling to this one phrase "originally there is not a single thing," and are liable to do just about anything; it's a wonder they don't fall into the views of crazy Zen! You must know that Zen actually has a rigorous process of practical work, and is not a matter of empty talk or wild self-approval; only then can you approach authentic Zen.
