Zen "Ensō" or "Circle of Life"
Principles of Zazen (Meditation)
"Studying Zen is zazen.
For zazen, one should have a quiet place...
Cast aside all involvements and discontinue the myriad affairs.
Good is not thought of; evil is not thought of.
It is not mind, intellect or consciousness; it is not thoughts, ideas or perceptions....
Having thus regulated body and mind, take a breath and exhale fully.
Sitting fixedly, think of not thinking.
How do you think of not thinking?
This is the art of zazen."
Dogen, 1243 CE*
