seated meditation
坐禅 (Jpn zazen )

    The practice of meditation in a sitting posture to perceive the truth by keeping the mind concentrated and unperturbed. This type of concentration exercise was carried out widely in ancient India and was incorporated into Buddhism by Shakyamuni, who sat in meditation when he attained enlightenment under the bodhi tree. This practice was introduced to China, and T'ient'ai (538-597) taught it as part of an integrated system of disciplines aimed at perceiving the true nature of one's mind. The Zen, or Ch'an, school attaches primary importance to the practice of seated meditation.
