Nichiren on the two Shakyamuni Buddhas and the Relative Sin of Devedatta

"As we have seen, Devadatta committed three grave offenses. But when he drew blood from the body of the Buddha, it was from the Buddha of the sutras preached prior to the Lotus Sutra, not the Shakyamuni who attained enlightenment in the inconceivably remote past. When he killed an arhat, it was an arhat of the pre-Lotus Sutra teachings, not a votary of the Lotus Sutra. And when he disrupted the harmony of the Buddhist Order, it was the Order that observed the pre-Lotus Hinayana precepts, not the Order of the great precepts of the Lotus Sutra, of perfect and immediate enlightenment. Though the earth opened up and Devadatta fell into the hell of incessant suffering, since he did not commit these three grave offenses against the Lotus Sutra, his punishment was not all that severe. Therefore in the Lotus Sutra it is predicted that he will become a Buddha named Heavenly King Thus Come One.: - Refuting Ryokan and Others
