From "Nichiren Seijin Goichidai Ki Gafu" (Picture Album of the Life of Holy Priest Nichiren). Yaku-o-maru wanted to gain the divine wisdom to be able to study the complicated Buddhist doctrines. When he was praying to Kyokuzo Bodhisattva, she appeared in front of him and gave him a crystal of the wisdom. After this incident, he could complete the study of the various Buddhist doctrines. --Tenrei Horiuchi (1903-1982)
