Buddhadāsa Bhikkhu was an influential Thai ascetic-philosopher of the 20th century. Known as an innovative reinterpreter of Buddhist doctrine and Thai folk beliefs, Buddhadasa fostered a reformation in conventional religious perceptions in Thailand and abroad.
Buddhadasa was broadly ecumenical, holding “all religions to be inwardly the same”, and encouraged Buddhists to transcend clinging to Buddhism as a “religion.”
