How to Cook Your Life is a translation of, and commentary on, Tenzo Kyokun by Eihei Dogen (1200-1253).
Tenzo Kyokun was written in the spring of the third year of the Katei era [1237] and it has often been considered one of Dogen's key texts.
The commentary on Dogen's text is by Kosho Uchiyama Roshi (1912-1998). Uchiyama Roshi was a senior discipe of the great Kodo Sawaki Roshi (1880-1965). In addition to being a Soto Zen priest he was also an origami master, the abbot of Antaiji Monastery, near Kyoto and the author of more than 20 books.
Zoketsu Norman Fischer, former abbot of the San Francisco Zen Center and founder and teacher of the Everyday Zen Foundation has said of this work "I am glad to see Uchiyama Roshi's classic commentary to Instructions for the Zen Cook back in print. Dogen's original text (here in Thomas Wright's lucid translation) is particularly applicable to everyday spirituality in the world, and Roshi's commentary, full of gritty, funny stories about his early days as a monk in pre- and post-war Japan, and charming tales from Buddhist and Japanese folklore, evidence a plain-speaking, shoot-from-the hip approach to Zen that is as refreshing now (possibly more so!) as it was when the book first came out. Zen masters of this full-bodied tasty vintage are hard to find these days!"
I heartily recommend this text both for the fine translation of the source text and for Kosho Uchiyama Roshi's commentary.
