Manual of Zen Buddhism is written by D.T.Suzuki, D.Litt. Professor of Buddhist Philosophy at Otani University in Kyoto, Daisetz Teitaro Suzuki, D.Litt., was born in 1870. He is currently arguably the greatest living expert on Buddhist philosophy and, without a doubt, the best authority on Zen Buddhism.
Dr. Suzuki writes authoritatively. He has not only studied original works in Sanskrit, Pali, Chinese, and Japanese but he also has a current understanding of Western philosophy in German and French as well as English which he speaks and writes effectively. He is also a Buddhist, in addition to being a scholar.
Despite the fact that he is not a Buddhist sect priest, he is revered in every temple in Japan for his spiritual knowledge, which everyone who has sat at his feet can attest to.
