Purnamaitrayaniputra

In Chapter 8, “Receipt of Prophecy by Five Hundred Disciples,” the Buddha predicts the future Buddhahood of Purna, one of his ten outstanding disciples. His full name is Purnamaitrayaniputra (son of Maitrayana). Maitrayana, which was the name of his mother, is Sanskrit for “the fullness of loving kindness.” He was foremost among the Buddha’s senior disciples in giving excellent Dharma talks. Purna was present in the assembly when the Buddha predicted the Buddhahood of the four bhikshus, and he was so moved by this that he came to stand near the Buddha as he was teaching. Then the Buddha looked at Purna and began to praise his fine qualities and practice, and predicted that he would become the Buddha Dharma Glow (Dharmaprabhasa) in a Buddha Land called Well Purified (Suvishuddha).
