Introduction to Zen Training: A Physical Approach to Meditation and Mind‑Body Training by Omori Sogen

Introduction to Zen Training presents Omori Sogen’s Sanzen Nyumon as a foundation for beginning Zen students. It addresses the physical and mental dimensions of sitting practice, including posture, breathing, drowsiness and the questions that arise when starting zazen.

The text also considers the place of a teacher, differences between Soto and Rinzai approaches, and maintaining attention away from the cushion. It concludes with commentaries on The Song of Meditation and the Ox-Herding Pictures. This is an introduction within a Buddhist practice tradition, not a medical treatment manual.
