Education
Terwiel was born in Ginneken near Breda in the Netherlands. After his military service in Netherlands New Guinea, Terwiel had to spend a few days in Bangkok due to a lack of transport capacity, which aroused his interest for Thailand. He completed his studies at the Utrecht University with a candidaats degree in Cultural Anthropology in 1965 and a doctorandus degree in anthropology, Pali and the History of Buddhism in 1967. For his doctoral studies, he moved to the Australian National University where he graduated with a Ph.D. in 1972. For his dissertation project, he had himself ordained as a Buddhist monk and lived for a year in a village monastery in central Thailand to explore ceremonies and religious practice of Thai Buddhism from an inner perspective.
