Luang Por Dattajivo (, ; ; born 21 December 1940), also known by his birth name Phadet Phongsawat () and former ecclesiastical title Phrarajbhavanajahn (, ), is a Thai Buddhist monk. He is the former deputy-abbot of Wat Phra Dhammakaya and the vice-president of the Dhammakaya Foundation, and was the observing abbot of the temple from 1999 until 2006, and again from 2011 until 2016. he was still widely considered the de facto abbot. He met Mae chi (nun) Chandra Khonnokyoong and Luang Por Dhammajayo in his student years, and they have been his teachers throughout his life. Luang Por Dattajivo was ordained in 1971, and quickly became a prolific author. He also took on a significant role in managing Wat Phra Dhammakaya. It was for this position that he was charged by the Thai military junta in 2017, when he refused to deliver Luang Por Dhammajayo to the authorities. This happened during the lockdown by the Thai junta, when abbot Luang Por Dhammajayo was sought for charges of receiving ill-gotten gains, charges which have been widely described as politically motivated.

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. In 1971, Phadet was ordained and
