Giun's Verse Comments was one of only two commentaries of the Treasury written during the Kamakura era, with the other being a prose analysis of the 75-chapter edition, called Prose Comments on the Treasury of the True Dharma Eye, often abbreviated to Distinguished Comments (Gosho). While Distinguished Comments fell into disuse rather quickly and was only revived nearly three hundred years later, the Verse Comments was circulated widely from the time of its composition and read by many Soto monks over the next couple of centuries. Offering poems and cryptic expressions that seek to capture the spiritual flavor and essential meaning of Dogen's thought as suggested in each chapter, the Verse Comments is crucial for understanding how Dogen's Treasury was received and appropriated in the religious and literary context of medieval Japan.

In this book, Steven Heine's careful interpretations, historical investigations, and theoretical reflections demonstrate the significance of Giun's writings in light of the history of pre-modern and modern commentaries on Dogen's masterwork, the Treasury of the True Dharma Eye.
