This chapter gives an overview of the origins, content, historical development, and important literary, religious, and philosophical implications of Giun’s Verse Comments on Dōgen’s Treasury of the True Dharma Eye, which was written in 1329 and published a century later and remained a key component of Sōtō Zen intellectual life for several centuries during the medieval period. It explains how Giun made decisive contributions to the restoration of Sōtō Zen at a key turning point in its early institutional expansion. These developments followed a few decades of decline caused by intense intrafactional rivalries at Eiheiji as part of the aftermath of Dōgen’s death compounded by the impact of a devastating fire in 1297 that destroyed many of the monastery’s architectural and textual treasures. By the Edo period, the significance of Giun’s Verse Comments was eclipsed by the Prose Comments (Goshō) on Dōgen’s Treasury written by Senne and Kyōgō.
