Of all the sūtras preached by all Buddhas throughout the lifetime of the Buddha and the Ages of the True Dharma, the Semblance Dharma, and the Latter Age of Degeneration after His passing, women could not attain Buddhahood without the Lotus Sūtra. This has been pointed out by Grand Master T’ien-t’ai of China, who had been guided directly by the Buddha on Mt. Sacred Eagle in India and attained enlightenment. In the seventh fascicle of his Words and Phrases of the Lotus Sūtra T’ien-t’ai declares that the other sūtras mention the enlightenment of men only, not of women, while the Lotus Sūtra explains the enlightenment of everyone regardless of sex, whether or not one is evil.
