Deep bows or prostrations. Normally done in a set of three and towards the altar, these are bows that lead immediately into a kneeling position and then quickly into a position with one’s forehead gently touching the floor. The hands, palms upwards, are raised in a gesture symbolic of lifting the Buddha’s feet over one’s head. It’s appropriate to cultivate an attitude of emptying, letting go, receptivity and gratitude. One should seek out instruction from a knowledgeable practitioner or teacher for the correct form and mental approach.
