 Ascetic Buddhist monks have been and continue to be found in Myanmar, and as in Thailand, they are known to pursue their own version of Buddhism, resisting the hierarchical institutionalized "sangha" structure of monasteries in Buddhism.In the Mahayana tradition, asceticism with esoteric and mystical meanings became an accepted practice, such as in the Tendai and Shingon schools of Japanese Buddhism.These Japanese practices included penance, austerities, ablutions under a waterfall, and rituals to purify oneself.
