Zen has no business with ideas.

Zen opens a man's eyes to the greatest mystery as it is daily and hourly performed; it enlarges the heart to embrace eternity of time and infinity of space in its every palpitation; it makes us live in the world as if walking in the garden of Eden

Zen abhors repetition or imitation of any kind, for it kills. For the same reason Zen never explains, but only affirms. Life is fact and no explanation is necessary or pertinent. To explain is to apologize, and why should we apologize for living? To live—is that not enough? Let us then live, let us affirm! Herein lies Zen in all its purity and in all its nudity as well.

Personal experience, therefore, is everything in Zen. No ideas are intelligible to those who have no backing of experience.

When the identity is realized, I as swordsman see no opponent confronting me and threatening to strike me. I seem to transform myself into the opponent, and every movement he makes as well as every thought he conceives are felt as if they were my own and I intuitively...know when and how to strike him.

Zen in it's essence is the art of seeing into the nature of one's being, and it points the way from bondage to freedom.

Zen is the spirit of a man. Zen believes in his inner purity and goodness. Whatever is superadded or violently torn away, injures the wholesomeness of the spirit. Zen, therefore, is emphatically against all religious conventionalism.
