Phra Dharmakosācārya (Nguam Indapañño) (Thai: พระธรรมโกศาจารย์ (เงื่อม อินฺทปญฺโญ); RTGS: Phra Thammakosachan (Ngueam Inthapanyo)), also known as Buddhadāsa Bhikkhu (Thai: พุทธทาสภิกขุ; RTGS: Phutthathat Phikkhu, 27 May 1906 – 25 May 1993) was a famous and 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 his home country, Thailand, as well as abroad. Buddhadasa developed a personal view that those who have penetrated the essential nature of religions consider "all religions to be inwardly the same", while those who have the highest understanding of dhamma feel "there is no religion".
