Phadet became involved in Thai black magic at the age of seventeen. In his student years at Kasetsart University, he would often hold organized public demonstrations of black magic for his fellow students. In the biographies of Wat Phra Dhammakaya it is described that every time a junior student, Chaiyabun (who later became known as Luang Por Dhammajayo), came to watch one of Phadet's demonstrations, the magic would not work. Phadet therefore become curious about Chaiyabun's mental powers, and decided to test Chaiyabun by bringing him to his black magic teacher. But even the teacher could not use his powers in Chaiyabun's presence. Phadet therefore wanted to learn more about Chaiyabun and the meditation he practiced. He felt inspired by Chaiyabun's sincerity in meditation and his adherence to the Buddhist five precepts. This was a turning point in his life, and from that moment on he has always been Chaiyabun's student and assistant, and they developed a solid friendship. Phadet gave up the practice of black magic and through Chaiyabun met Mae Chi Chandra. He trained in meditation with Mae Chi Chandra for years.
