Do not judge things as good or evil, and cease such distinctions as "is" and "is not." Halt the flow of the mind, and cease conceptualizing,
thinking and observing. Don't sit in order to become a Buddha (enlightened), because becoming a Buddha has nothing to do with such things
as sitting or lying down.
in the room that you use for zazen, spread some thick mats and place a firm, round pillow on them. Sit on the pillow with your legs crossed either in the full-lotus position or in the half-lotus position. This means [in the full-lotus position] that you place your right foot on your left thigh, and your left foot on your right thigh. In the half-lotus position, you just put your left foot on your right thigh [with the right foot on the mat beneath your left thigh].
