📖 Overview
Transmission of Light (Denkoroku) is a 13th century Zen text written by Japanese Zen master Keizan Jokin. The book presents 53 short chapters that trace the lineage of Zen Buddhism from Shakyamuni Buddha through successive generations of teachers.
Each chapter follows a consistent format - introducing a teacher, relating a key encounter or dialogue that led to their awakening, and concluding with a verse commentary. The chapters move chronologically through Indian, Chinese and Japanese Zen masters, documenting how the dharma was passed from teacher to student across centuries and cultures.
The text serves as both a historical record and a collection of teaching stories known as koans. Keizan composed this work while serving as the head teacher at Yokoji monastery, drawing from earlier Chinese lamp transmission records and adding his own interpretations.
The book explores core Zen themes of direct transmission beyond words, the nature of enlightenment, and the relationship between teachers and students. Through these biographical accounts, it illuminates how wisdom is conveyed from one generation to the next while remaining fresh and immediate.
