Even though there is a difference between whether one strays from it or realizes it, nevertheless the basic source is one. That is why it is said that the Dharma refers to the minds of living beings. This open, silent mind is not more in sages or less in ordinary people. Thus it is said that in sages it is knowledge that is nevertheless not flashy, and while it is hidden in the ordinary mind, yet it is not dimmed.
Since it is not more in sages or less in ordinary people, how could the Buddhas and Zen masters be different from other people? What makes them different from other people is simply that they are able to guard their own minds and thoughts. If you can trust completely, your feelings of doubt will stop all at once, allowing a healthy will to emerge, so that you can discover real true vision and understanding, personally tasting its flavor, so that you naturally arrive at the stage of spontaneous acknowledgment.
This is the understanding of someone who is going to cultivate the mind; there are no more stages or steps, so it is called sudden. It is like the saying that real faith is attained only when there is conformity to perfect Buddhahood in the basis of your faith.
Question: If there are no more stages after having realized this principle, why the need for subsequent practice, gradual cultivation, and gradual perfection?
Answer: I have already explained the meaning of gradual practice after enlightenment, but seeing that your doubts have not yet been resolved, I will explain it again. You should purify your mind so as to listen truly and hear accurately.
Ordinary people have been revolving in circles since time immemorial, being born and dying in five courses of existence. Because of clinging fixedly to self-images, false ideas, and misperceptions, the habits of illusion eventually become second nature to them. Even if they suddenly awaken in this life and realize that their essential nature is fundamentally empty and silent, no different from the Buddhas, nevertheless past habits are difficult to remove at once.
Therefore they rage and rejoice as they encounter irritating and pleasing situations; judgments of right and wrong arise and pass away in profusion, and afflictions caused by outside influences are no different from before. If they do not make use of the power within transcendent insight, how can they quell ignorance and reach the state of great rest and tranquility? As it is said, “When suddenly awakened, although you are the same as Buddha, the energy of many lifetimes of habits is deep seated. Though the wind stops, the waves still billow, though noumenon is manifest, thoughts still invade.”
Master Gao said, “Time and again those who have sharp faculties awaken without much effort, then they become complacent and neglect further cultivation. Eventually they drift back into their former confusion, unable to escape revolving in circular routines.” So how can we neglect subsequent cultivation because of a single awakening?
Therefore, after awakening it is necessary to always observe and examine yourself. When errant thoughts suddenly arise, do not go along with them at all, reduce them, reduce them, until you reach the point of non-contrivance, which alone is the ultimate end. This is the ox-herding practice carried out by all illuminates after their enlightenment. Even though there is subsequent cultivation, they have already realized sudden enlightenment.
Errant thoughts are fundamentally empty; the essence of mind is fundamentally pure. To stop evil over and over without any stopping, and cultivate goodness over and over without any cultivating, is true stopping and cultivation. Therefore it is said that even as you fully cultivate myriad practices, only no thought is to be considered a basis.
In making a general distinction between the meanings of attaining enlightenment first and then cultivating it afterward, Guifeng said, “You suddenly realize this essence is originally free from affliction; the essence of uncontaminated knowledge is inherently complete, no different from Buddha. To cultivate practice based on this is called the Zen of the highest vehicle, and it is also called the pure Zen of those who realize suchness. If you can cultivate its practice moment to moment, in a gradual manner you will naturally attain hundreds and thousands of spiritual states. This is the Zen that has been transmitted in the school of Bodhidharma.” Thus sudden enlightenment and gradual cultivation are like the two wheels of a chariot; it will not work if one is missing.
Some people, not knowing the essential emptiness of good and evil, think practical cultivation of mind means to sit rigidly immobile, subduing body and mind, like a rock placed on top of grass. This is ludicrous. That is why it is said that followers cut off confusion in every state of mind, yet the mind that does the cutting off is a brigand.
That is why it is said that we should not fear the arising of thoughts, just fear being slow to notice. It is also said, “When thoughts arise, immediately notice them; once you become aware of them, they no longer are there.”
Thus in the experience of enlightened people, even if there are afflictions associated with the external world, all of them produce the most subtle and refined flavor. Just be aware that confusion has no basis, that the illusory triple world is like smoke swirling in the wind, that the phantasmagoric six sense fields are like hot water melting ice.
If you can practice this moment to moment, not neglecting to be attentive, seeing to it that concentration and insight are equally sustained, then love and hate will naturally lighten and thin out, while compassion and wisdom will naturally increase in clarity; sinful deeds will naturally end, while meritorious actions will naturally progress.
When afflictions are ended, then birth and death stop. If subtle flowings are permanently ended, the great knowledge of complete awareness alone remains, radiantly clear. Then you manifest millions of emanation bodies in the lands of the ten directions, responding to potential as sensed like the moon appearing in the highest skies with its reflection distributed throughout myriad waters, functions adaptively to liberate boundless beings with affinity, joyful and happy, without sorrow. This is called great enlightenment, honoring the world.
