Approach to Zen
by Uchiyama, Kōshō · 1973

(from the inside jacket) This book....offers the reader practical guidance, instruction, and encouragement to go on sitting. Uchiyama roshi has created an especially clear, straight-forward presentation which minimizes the technical Buddhist terminology. This also keeps zazen from seeming esoteric and shows that it should be part of everyone,s ordinary life.
