Suzuki Shosan was a samurai who at midlife became a Zen monk. He evolved an original teaching style imbued with the warrior spirit, emphasizing dynamic activity over quiet contemplation, urging his students to realize enlightenment in the midst of their daily tasks. Today, many who are attracted to Zen but cannot set apart the necessary time from the lives they lead may find appeal in his unorthodox approach.
If you read books on Zen, and would like an unusual take on things, this book may offer it. Suzuki Shosan was a samurai who resigned to study the "Way". For him, mindfulness of death and general preparedness was the main point. I liked the way, in particular, that he cast aside his "enlightenment experiences" as useless. Sometimes, just when he seems not as deep as some other Zen heros, he surprises you. So: a good, somewhat unorthodox and refreshing read.
