Most interesting to me, with respect to the book's biographical mission, were two things: (1) the description of Suzuki's Zen training and work in Japan; (2) the details about how Suzuki "grew" Zen Buddhism in San Francisco, with some mentions of people I either knew personally, or knew of, including our current Governor.
Interspersed among the biographical details are little "sayings" of Suzuki-Roshi, as his disciples called him. These, too, make the book worthwhile:
Enlightenment is not a complete remedy.
The secret of Soto Zen is just two words: not always so.
Funny guy, that Crooked Cucumber! And pretty smart!
