Grand Master T’ien-t’ai, who thoroughly studied the holy teachings of the Buddha’s lifetime, declares, “In sūtras other than the Lotus Sūtra, attainment of future Buddhahood was guaranteed only to bodhisattvas exclusive of the Two Vehicles. … The guarantee of future Buddhahood was granted only to virtuous people, not evil people. In the Lotus Sūtra, on the contrary, the guarantee of future Buddhahood was made both to virtuous and evil people.”
