About Fukan zazengi

Fukan zazengi, also known by its English translation Universal Recommendation for Zazen, is an essay describing and promoting the practice of zazen written by the 13th century Japanese Zen monk Eihei Dōgen. The date of its composition is unclear, and the text evolved significantly over the author's lifetime. It is written in Classical Chinese rather than the Classical Japanese Dōgen used to compose his famous Shōbōgenzō.
