Anything can become a meditation — cooking or washing your clothes, any activity can be transformed into meditation. And the real sannyasin, the real seeker, will transform all his acts into meditation. Only then, when meditation spreads over all your life, not only when you are awake in the day — slowly slowly it starts penetrating and permeating your being in sleep too — when it becomes just part of you, like breathing, like your heartbeat, then, only, have you attained to the discipline, to the essential discipline of Zen.
