Gisan Tonin

Gisan Tonin was a Soto Zen master who served in the lineage of teachers maintaining the tradition at Eiheiji and its branch temples. He contributed to the training of monks and the preservation of the Soto school's meditative practices during his period of activity.

Tonin's role in the Soto lineage reflects the school's emphasis on continuous, generation-to-generation transmission as the vehicle for preserving the authentic spirit of practice. Each abbot and teacher in the Soto succession carried the responsibility of maintaining both the institutional structure and the contemplative depth of the tradition, ensuring that Dogen's vision remained alive and accessible.
