Phra Sangkatjaai, whose image is often mistaken for that of Budai or Huan Xi Fo, the Chinese ‘smiling buddha’. He is regularly depicted meditating in a sitting pose with both hands on his belly. In Sanskrit, his name is Maha Katyayana (fig.).

Whereas Huan Xi Fo is bald and dressed in a robe that covers both shoulders but shows his belly, Phra Sangkatjaai clearly has hair and is dressed in a robe that covers only one shoulder as well as his belly. He is one of the Ten Principal Disciples.
