Hòa Hao Buddhism is a religion based on the teachings of the Buddha. It was founded by Prophet Huynh Phu So in 1939. This story was when the Master began to give lectures openly, Mr. Chin of My Hoi Ðong village and his son Mr. Bay Dut, both came to take refuge with the Master. On the day when Mr. Chin and his son Bay Dut came to visit, the Master asked them to go bathing with Him. The Master asked Mr. Bay Dut to help rub and clean His back. Obeying His command, Mr. Bay rubbed much harder, when He turned his face around, Mr. Bay saw an old man. From a yong man, suddenly the Master became an old man with white hair and beard. For Mr. Bay, it was unimaginable.
