Realization of Virtue ［覚徳比丘］ ( Kakutoku-biku): A monk described in the “Diamond-like Body” (second) chapter of the Mahāparinirvāna Sutra, the forty-volume Chinese version of the Nirvana Sutra translated by Dharmaraksha in 421. His Sanskrit name is unknown, for only fragments of the Sanskrit text are extant. According to the sutra, a considerable time after the death of the Buddha Joy Increasing, the correct teaching of Buddhism was about to perish. Realization of Virtue strove to protect the teaching and was attacked by many evil monks and their followers. The king Possessor of Virtue defended him, enabling Realization of Virtue to escape, but the king died of the wounds he sustained. According to the sutra, because of their devotion to Buddhism, the king Possessor of Virtue was reborn as Shakyamuni Buddha and the monk Realization of Virtue as Kāshyapa Buddha.
