Founding Tendai Buddhism — Saicho and the Influence of Enryakuji on Japanese Buddhism
Saicho traveled to Tang China in 804 alongside Kukai, studied the Tiantai teachings, and returned to Japan. Opening Enryakuji temple on Mount Hiei, he cultivated Tendai Buddhism into the mainstream of Japanese Buddhism. All the founders of Kamakura Buddhism — Honen, Dogen, Shinran, and Nichiren — trained at Mount Hiei, leading Saicho's Tendai Buddhism to be called 'the womb of new Kamakura Buddhism.' He left the words 'Forget yourself to benefit others — this is the root of compassion.'
