Zazen is seated meditation-the opposite of contemplation-the emptying of the mind of all thoughts in order simply to be. In the midst of all evil, not a thought is aroused in the mind-this is called za. Seeing into one's Self-nature, not being moved at all-this is called Zen.
HuinengA finger points at the moon, but the moon is not at the tip of the finger. Words points at the truth, but the truth is not in words.
