Ajahn Mun Bhuridatta Mahathera was one of his most well-known students. The two were known to often travel together, wandering throughout the forests of Thailand in the “tudong” tradition of monks who leave behind the more sedentary monastery life and take up many (if not all) of the thirteen dhutanga austerities or ascetic practices allowed by the Buddha in the Pali canon.

Ajahn Sao was greatly influenced, in his own practice and in teaching his disciples, by the methods advocated by Somdet Phra Vanarat Buddhasiri (1806-1891), one of the founders of the Dhammayut order. The latter’s teachings are found summarized in his treatise “Caturarakka Kammathana,” or “The Four Objects of Meditation That Give Protection.”

After his cremation, his bone fragments were distributed to people around the Thai provinces. According to his followers, they transformed into crystal-like relics (Pali: Sarira-Dhatu) in various hues.[citation needed]
