Once the Bodhisatta was a famous teacher of Takkasilā, and among his pupils was one named Pāpaka. He, wishing for a less ill omened name, consulted his teacher. The Bodhisatta suggested that Pāpaka should travel and find a suitable name. He came back a wiser man, for he discovered that "Jīvakas" died and that "Dhanapālīs" grovelled in poverty the name signified nothing.
The story was related in reference to a monk called Pāpaka who wished to change his name. The two are identical. J.i.401ff.
