The real Way circulates everywhere; how could it require practice or enlightenment? The essential teaching is fully available; how could effort be necessary? Furthermore, the entire mirror is free of dust; why take steps to polish it? Nothing is separate from this very place; why journey away?
And yet, if you miss the mark even by a strand of hair, you are as distant as heaven from earth. If the slightest discrimination occurs, you will be lost in confusion. You could be proud of your understanding and have abundant realization, or acquire outstanding wisdom and attain the way by clarifying the mind. Still, if you are wandering about in your head, you may miss the vital path of letting your body leap.
You should observe the example of Buddha Shakyamuni of the Jeta Grove, who practiced sitting up straight for six years even though he was gifted with intrinsic wisdom. Still celebrated is the Master Bodhidharma of Shaolin Temple who sat facing the wall for nine years, although he had already received the mind seal. Ancient sages were like this; who nowadays does not need to practice as they did?
Hence, you should stop searching for phrases and chasing after words. Take the backward step and turn the light inward. Your body-mind of itself will drop off and your original face will appear. If you want to attain just this, immediately practice just this.
For zazen, a quiet room is appropriate. Drink and eat in moderation. Let go of all involvements and let myriad things rest. Do not think good or bad. Do not judge right or wrong. Stop conscious endeavor and analytic introspection. Do not try to become a buddha. How could being a buddha be limited to sitting or not sitting?
In an appropriate place for sitting, set out a thick mat and put a round cushion on top of it. Sit in either the full- or half-lotus posture. For the full-lotus posture, first place the right foot on the left thigh, then the left foot on the right thigh. For the half-lotus posture, place the left-foot on the right thigh. Loosen the robes and belts and arrange them in an orderly way. Then place the right hand palm up on the left foot, and the left hand on the right hand, with the tips of the thumbs lightly touching each other.
Sit straight up without leaning to the right or left and without bending forward or backward. The ears should be in line with the shoulders and the nose in line with the navel. Rest the tongue against the roof of the mouth, with lips and teeth closed. Keep the eyes open and breathe gently through the nose.
Having adjusted your body in this manner, take a breath and exhale fully, then sway your body to left and right. Now sit steadfastly and think not-thinking. How do you think not-thinking? Beyond thinking. This is the essential art of zazen.
The zazen I speak of is not learning meditation. It is simply the dharma gate of enjoyment and ease. It is the practice-realization of complete enlightenment. Realize the fundamental point free from the binding of nets and baskets. Once you experience it, you are like a dragon swimming in the water or a tiger reposing in the mountains. Know that the true dharma emerges of itself, clearing away hinderances and distractions.
When you stand up from sitting, move your body slowly and rise calmly, without haste. We understand from past precedents that going beyond ordinary and sacred, where sitting and standing are effortless and boundless, depends solely on the power of zazen.
Furthermore, bringing forth the turning point by using a finger, a pole, a needle, or a mallet, or leading people to enlightenment with a whisk, a fist, a stick, or a shout, cannot be understood by discriminatory thinking. How can it be understood by the use of supernatural powers? Zazen is an awesome presence outside form and color. How is it not the path preceding concept?
Thus, do not be concerned with who is wise and who is stupid. Do not discriminate the sharp from the dull. To practice wholeheartedly is the true endeavor of the way. Practice-realization is not defiled with specialness; it is a matter for every day.
Now, in this world and in other worlds, in India and China, buddha ancestors equally carry the buddha seal and teach to sit immersed in steadfastness. Although circumstances may vary in a thousand ways, wholeheartedly practice Zen, giving yourself fully to the way. Why give up the sitting platform of your own house and wander uselessly in the dust of a remote land? Once a wrong step is taken, you depart from the way.
Having received human life, do not wast the passing moments. Already upholding the buddha way, why would you indulge in the sparks from a flint? After all, form is like a dewdrop on the grass. Human life is like a flash of lightening , transient and illusory, gone in a moment.
Honored practitioners of Zen, please do not grope for the elephant or try to grasp the true dragon. Strive to hit the mark by directly pointing. Revere the mind that goes beyond study and surpasses all doings. Experience the enlightenment of the buddhas, correctly inheriting the samadhi of the ancestors. Practice thusness continuously, and you will be thus. The treasury will open of itself for you to use as you wish.
