From the moment of [Nichiren’s] recovery [after 21 days of prayer and fasting before the image of Kokuzo Bosatsu], a new clarity began to enter his life. Through his diligent studies, he began to recognize differences among the various sutras. This recognition was based upon what he called “The Treasured Gem” – a gift of knowledge divided into two parts. The first part was drawn from the Nirvana Sutra that said: “Rely on the Dharma, and not on any person.” Thus, a man could never be misled by clever people. The second part was to rely on reason, on written proof, and finally, on that proof drawn from one’s own experience.
