In the words of Zen Master Mumon: "You will know yourself and for yourself only." . . . There is a beautiful Zen Verse about knowing for yourself and for yourself only:
By acquiring the marrow, you will know the clarity of what you found;
Lun-pien still possesses subtleties he does not pass on.
You can go deep and directly experience the essence of yourself, of life, and of the universe. The clarity of your experience makes you aware of infinite subtleties — each perceived moment to moment.
— Ellen Birx, Healing Zen
