Phra Sangkajai / Phra SangkachaiIn Thailand, Budai is sometimes confused with another similar monk widely respected in Thailand, Phra Sangkajai or Sangkachai. Phra Sangkajai, a Thai spelling of Mahakaccayanathera was a Buddhist Arhat (in Sanskrit) or Arahant (in Pali) during the time of the Lord Buddha. Lord Buddha praised Phra Sangkadchai for his excellence in explaining sophisticated dharma (or dhamma) in an easily and correctly understandable manner. Phra Sangkajai also composed the Madhupinadika Sutra.
One tale of the Thai folklore relates that he was so handsome that once even a man wanted him for a wife. To avoid a similar situation, Phra Sangkadchai decided to transform himself into a fat monk. Another tale says he was so attractive that angels and men often compared him with the Buddha. He considered this inappropriate, so disguised himself in an unpleasantly fat body.
Although both Budai and Phra Sangkajai may be found in both Thai and Chinese temples, Phra Sangkajai is found more often in Thai temples, and Budai in Chinese temples. Two points to distinguish them from one another are:
Phra Sangkajai has a trace of hair on his head (looking similar to the Buddha's) while Budai is clearly bald.
Phra Sangkajai wears the robes in Theravadin Buddhist fashion with the robes folded across one shoulder, leaving the other uncovered. Budai wears the robes in Chinese style, covering both arms but leaving the front part of the upper body uncovered.
