22.1 Enryakuji Marathon Monks 回峰行 Monks 'circling the mountain’ is a tradition at Mt Hiei and Enryakuji and goes back to the practice of the warrior monks of old. Enryakuji has always been known for its esoteric and austere mountain practices. Devotion and selflessness are what’s important in the Tendai Sect of Buddhist and it is thought that this can be achieved by circling the mountain on foot as the ultimate expression of devotion. These practices include a twelve year course of circling Mt Heiei before dawn, and finally fasting for ten days without water or sleep. Very few monks have ever completed this goal in the temple's history, yet many still make the attempt.
