佛祖統紀 17.36

17.36

Dharma Master Shunjō was a man of Japan. He had previously transmitted the Yoga esoteric teachings. (During the Yuanhe era of the Tang, his countryman Kūkai entered China and received the esoteric teachings from Huiguo, a disciple of Amoghavajra.) Later he crossed the sea and came to China, ascending Lingshan to visit Beifeng. He studied the Tiantai lineage, holding the scriptures and receiving instructions, thoroughly penetrating their purport. At the beginning of the Kaixi era, the northern barbarians invaded the border; Shunjō proposed to Beifeng that he wished to establish an altar and recite mantras, just as Amoghavajra had lifted the siege of Anxi. At that time opinion was weak and hesitant, and in the end it could not be carried out. Beifeng then had him dispatch disciples back to his country to retrieve the teachings of the Five Divisions previously transmitted to China, but his disciples were drowned in the sea. (These are the Dharma heirs of Dharma Master Beifeng Yin. There were sixteen persons; the previous eleven were lost, and the later three were lost, leaving only this Dharma master and Zhao Yansu.)
