The disciple's name was Pindola. The story foes like this. A wealthy man put a clay bowl on a tall pole, saying anyone who could take the bowl down could have it. Pindola levitated to the top of the pole and took the bowl in order to increase the fame and reputation of the Buddha and his sangha. When he showed the bowl to the Buddha, he broke the bowl into pieces and made a Vinaya rule forbidding the demonstration of psychic powers to lay persons.
According to tradition Pindola is one of the 16 arhats who pledged to protect the dharma after Buddha's death.
Lamrim, lojong, and mahamudra are the unmistaken path.
