If you have a glass full of liquid you can discourse forever on its qualities, discuss whether it is cold, warm, whether it is really and truly composed of H2O, or mineral water, or saki. Zazen is drinking it.
Taisen Deshimaru
No thought, no action, no movement, total stillness: only thus can one manifest the true nature and law of things from within and unconsciously, and at last become one with heaven and earth.
Lao Tzu
We are sick with fascination for the useful tools of names and numbers, of symbols, signs, conceptons and ideas. Meditation is therefore the art of suspending verbal and symbolic thinking for a time, somewhat as a courteous audience will stop talking when a concert is about to begin.
Alan Watts
Teach us to care and not to care
Teach us to sit still.
T.S. Eliot
