There is no finger. There is no moon. This is the fundamental Zen breakdown of the problem, at least. In Theravadan buddhism, the self is like a stick hut standing in a field: you can break it down and deconstruct it stick by stick, and thereby attain Buddhahood. In Zen, there is no hut. You are Buddha, right here and now.
The Zen "approach" cannot be explained, much like the teachings of Krishnamurti or Ramana Maharshi, or, as in the case of this thread, the psychedelic experience, or, as in the case of this life, oneself.
