“The more one concentrates on breathing, the more the external stimuli fade into the background... In due course one even grows immune to larger stimuli, and at the same time detachment from them becomes easier and quicker. Care has only to be taken that the body is relaxed whether standing, sitting or lying, and if one then concentrates on breathing one soon feels oneself shut in by impermeable layers of silence. One only knows and feels that one breathes. And, to detach oneself from this feeling and knowing, no fresh decision is required, for the breathing slows down of its own accord, becomes more and more economical in the use of breath, and finally, slipping by degrees into a blurred monotone, escapes one's attention altogether.”
― Eugen Herrigel, Zen in the Art of Archery
