This takes place morning and evening, usually for half an hour. During retreats, half-hour sessions of sitting meditation are separated by short ten-minute breaks of walking meditation. For sitting, the classic Buddhist posture is taught: legs crossed, back straight, eyes half closed, hands in mudra, mind aware of breathing.
In the Kwan Um School of Zen, meditation is not primarily dependent on the attitude of the body, but that of the mind. During sitting meditation the practitioner continually asks a great question such as ‘What am I?’ Faced with the power of this question, thinking stops and Don’t-Know appears. Don’t-Know is the name of the mind before thinking. We can call it the mind, Buddha, original nature, the absolute, holiness, energy or consciousness, but originally this point has neither name nor form. Cutting off all thoughts and returning to the Don’t-Know mind allows the Zen practitioner to go back to their original being.
