RULES FOR ZAZEN

Practicing Zen is zazen. For zazen, a quiet place is suitable. Lay out a thick mat. Do not let in drafts or smoke, rain or dew. Protect and maintain the place that contains your body. Day or night, the place of sitting should not be dark; it should be kept warm in winter and cool in summer.

Set aside all involvements and let the myriad things rest. Zazen is not thinking of good, not thinking of bad. It is not conscious endeavor. It is not introspection. Do not desire to become a buddha. Let sitting or lying down drop away. Be moderate in eating and drinking. Mindful of the passing of time, engage yourself in zazen as though saving your head from fire.

When sitting in zazen, wear the kasaya (monastic robe) and use a round cushion. The cushion should not be placed all the way under the legs but only under the buttocks. In this way the crossed legs rest on the mat and the backbone is supported by the round cushion. This is the method used by all buddha ancestors for zazen.

Sit either in the half-lotus position or in the full-lotus position. For the full-lotus put the right foot on the left thigh and the left foot on the right thigh. The toes should lie along the thighs, not extending beyond. For the half-lotus position, simply put the left foot on the right thigh.

Loosen your robes and arrange them in an orderly way. Place the right hand on the left foot and the left hand on the right hand, with the ends of the thumbs lightly touching each other. With the hands in this position, place them close to the body so that the joined thumb tips are at the navel.

Straighten your body and sit upright. Do not lean to the left or right; do not bend forward or backward. Your ears should be in line with your shoulders, and your nose in line with your navel.

Rest your tongue against the roof of your mouth and breathe through your nose. Lips and teeth should be closed. Eyes should be open, neither too wide nor too narrow. Having adjusted body and mind in this manner, take a breath and exhale fully.

Sit solidly in samadhi and think not thinking. How do you think not thinking? Beyond thinking. This is the art of zazen.

Zazen is not learning to concentrate. It is the dharma gate of great ease and joy. It is undivided practice-realization.
