āsana. From the Sanskrit, meaning "sitting". The importance of posture for spiritual purification and progress is much emphasized in yogic and other types of Indian religious thought and practice. The concept has counterparts in the West, e.g., in Catholic ritual, in which posture has a significance comparable to that of speech and functions similarly, so that both minister to the completeness of liturgical expression and the beneficent effect on the development of the interior life.

Geddes MacGregor, Dictionary of Religion and Philosophy, New York: Paragon House, 1989

āsana

(Sanskrit). A yogic posture which provides a seat for meditational practice. The most common example is the ‘lotus posture’ (padmāsana) in which both feet rest on top of the thigh of the opposite leg.
