How to Sit
Regarding the actual practice of zazen, Zongze writes as follows in the Zazengi:
When you wish to sit in meditation, first put down a thick cushion in a quiet place. Wear your robe and belt in a nonconstricting manner, and comport yourself properly. Then sit in the full lotus position.
For those living in the city, a truly quiet place to meditate is not always available. Generally one must settle for a place where outside sounds are at a minimum—in a study, for example, or a bedroom. Those who have a garden may wish to sit by its side, where they can be as close as possible to nature.
Placing religious objects in the meditation room helps to create an appropriate atmosphere. In Zen monasteries an image of Manjusri, the Bodhisattva of Wisdom, is always placed at the head of the Zen meditation hall, but in an ordinary household one may substitute an appropriate piece of calligraphy or a hanging scroll depicting of a buddha or bodhisattva.
Loose-fitting clothes are best for zazen. If Western-style clothing is worn instead of robes, then the belt should be loosened a notch or two and the necktie removed. It is important not to be slovenly in appearance or behavior, however, which is why the
Zazengi stresses that you must “comport yourself properly.” A careless attitude leads to zazen
that is lacking in focus.
Regulating the Body
The zazengi mentions two ways in which to arrange the legs when sitting in zazen: the full-lotus position and the half-lotus position. In the former, place the right foot on the left thigh and the left foot on the right thigh (or vice versa), pulling the feet in as close to the trunk as possible so that the heels rest near stomach and the soles point upward. Center the back by rocking from right to left, gradually decreasing the arcs until one feels centered and balanced.
Next, lean forward from the hips with the back held straight. Raise the trunk once again to the upright posture, leaving the pelvis tipped forward and the lower back curved in. This posture, once one is accustomed to it, creates the most relaxed and stable foundation for zazen.
Those who can manage neither the full- or half-lotus positions may kneel in the Japanese seiza style. Sitting on a zafu placed between the legs allows one to sit comfortably in seiza for longer periods of time. For people with injuries or who for whatever reason cannot manage any of these positions, it is possible to meditate quite well in a chair. The back should be straight, as described above, and the pelvis should be a bit higher than the knees. Placing a cushion on the seat of the chair can raise the pelvis and make sitting more comfortable.
The right hand should be placed palm up on the lap; the left hand should be placed palm up on the right hand. The two hands should rest against the lower abdomen. The tips of the thumbs should touch with a light pressure, forming an egg-shaped oval. This hand position is known as the cosmic mudra.
Keep the eyes open. Look straight forward at first, then drop the gaze 45 degrees till one is looking at a point on the floor about two meters in front of one. The eyes should have the half-open appearance of the eyes on a buddha statue. Sitting with eyes completely closed should be avoided, as it can easily lead to drowsiness or a lack of focus.
Regulating the Breath
Once the body’s posture is balanced and settled, attention should be turned to the breathing. In many ways the breathing, which links and integrates body and mind, is the most important aspect of zazen. In zazen, one becomes fully aware of and open to each in-breath and out-breath. The exhalation should be long, deep, and relaxed, with the breath allowed to go out as far as it naturally wishes to go. At that point the inhalation will occur naturally. The breathing, both in and out, should be free of all tension and should flow from the tanden. It can help to breathe with the sense that one is simply connecting the air inside of the body and outside of the body.
Regulating the Mind
Regarding regulation of the mind, the Zazengi advises as follows:
Keep your lower abdomen relaxed. Do not think of “good” or “evil.” When a thought arises be aware of it; as soon as you are aware of it, it will disappear. If for long periods you forget all ties, you will naturally become One. These are the essential techniques of zazen.
Sit with a feeling of complete openness, with the body and mind settled in the tanden and free of all tension. When stray thoughts, fantasies, and judgments of right and wrong arise, illuminate them with an awareness that is relaxed but fully awake. Continue in this from one moment to the next, from one sitting period to the next, until one’s mind is clear and open. Look into the source of the mind as it is prior to thought.
Although zazen can explained by dividing it into the elements of body, breath, and mind, it should be remembered that these three can not really be divided. Body and mind, linked by breath, work together as one. Whether you consider the body, the breath, or the mind, the other two elements are always present. A posture that is straight, balanced, and relaxed will help bring about a mind that open and fully aware; a mind that is open and fully aware will help bring about a posture that is balanced and straight.
