Shunryu Suzuki said this quote

“ Even in zazen you will lose yourself. When you become sleepy, or when your mind starts to wander about, you lose yourself. When your legs become painful—“Why are my legs so painful?”—you lose yourself. ”-“You just sit in the midst of the problem; when you are a part of the problem, or when the problem is a part of you, there is no problem, because you are the problem itself. The problem is you yourself. If this is so, there is no problem.”-“When you start to wander about in some delusion which is something apart from you yourself, then your surroundings are not real anymore, and your mind is not real anymore. If you yourself are deluded, then your surroundings are also a misty, foggy delusion. Once you are in the midst of delusion, there is no end to delusion. You will be involved in deluded ideas one after another. Most people live in delusion, involved in their problem, trying to solve their problem. But just to live is actually to live in problems. And to solve the problem is to be a part of it, to be one with it. ”
