Seated to one side, the Buddha said to Nandiya the Sakyan:
“Nandiya, a noble disciple who has four things is a stream-enterer, not liable to be reborn in the underworld, bound for awakening.

A noble disciple who has these four things is a stream-enterer, not liable to be reborn in the underworld, bound for awakening.”
