Thus from the standpoint of Zen the Buddha “never said a word,” despite the volumes of scriptures attributed to him. For his real message remained always unspoken, and was such that, when words attempted to express it, they made it seem as if it were nothing at all. Yet it is the essential tradition of Zen that what cannot be conveyed by speech can nevertheless be passed on by “direct pointing,” by some nonverbal means of communication without which the Buddhist experience could never have been handed down to future generations.
