For many years, Nichiren Shonin traveled all over Japan, visiting all the great temples and monasterie of his day in order to further his training. In these places, Nichiren Shonin acquired firsthand experience of all the forms of Buddhism practiced in Japan, including esoteric ceremonies, sitting meditation, chanting the name of the Buddha of Infinite Light, and the strict discipline of the monastic precepts. More importantly, he studied the sutras in order to see for himself what Shakyamuni Buddha actually taught. After many years of study, Nichiren Shonin concluded tham the Lotus Sutra was the culmination of Shakyamuni Buddha’s teachings, wherein the ultimate truth of Buddhism is clearly expounded.
