佛祖統紀 12.26

12.26

法師源信。日本國十大禪師也。咸平六年。遣其徒寂照。持教義二十七問。詣南湖求決。法智為其一一答釋。照欣領歸國。信大服其說。西向禮謝（此下本紀遺失源清一人）。

Dharma Master Genshin was one of the ten great Chan masters of Japan. In the sixth year of Xianping, he dispatched his disciple Jakuchō with twenty-seven questions on doctrinal principles to visit Nanhu and seek resolution. Fazhi answered and explained each one for him. Chō joyfully received them and returned to his country; Shin greatly submitted to his explanations and bowed in gratitude facing west. (Below this, the Basic Annals omitted one person, Genqing.)
