I recently read some lectures by Pat Phelan about Dogen’s Fukanzazengi, where she indicates that Dogen wrote three zazen “users manuals”, that are available in English from Stanford’s Soto Text Translation Project:
- Zazengi (Principles of Zazen)
- Zazenshin (Lancet of Zazen)
- Fukanzazengi (Universally Recommended Instructions for Zazen)
The translators’ notes and supplemental notes are especially helpful to understand the historical Zen background/context of Dogen’s references.
I hope you too find these excellent Dogen writings an encouragement in your practice.
