The Marrow of Zen

"In the zazen posture, your mind and body have great power to accept things as they are, whether agreeable or disagreeable. When you feel disagreeable it is better for you to sit. There is no other way to accept your problem and work on it. Whether you are the best horse or the worst, or whether you posture is good or bad is out of the question. Everyone can practice zazen, and in this way work on his problems and accept them." Shunryu Suzuki
