Women, who were thus despised in various sūtras, were able to attain Buddhahood as soon as Bodhisattva Mañjuśrī expounded the character “myō.” This was so mysterious that Bodhisattva Accumulated Wisdom, the first disciple of the Buddha of Many Treasures in the Treasure Purity World, and Venerable Śāriputra, the wisest disciple of Śākyamuni Buddha, argued against the daughter of a Dragon King to be made a Buddha in the spirit of the various Hinayāna and Mahāyāna sūtras expounded by the Buddha during the 40 years or so of His preaching. Their efforts were in vain, and the daughter of a Dragon King ultimately became a Buddha. The statement in the Flower Garland Sūtra, “Women extirpated the seeds of Buddhahood” and that of the Nirvana Sūtra, “As all rivers are twisted, so are women’s mind” were both invalidated. Both opinions of the Sūtra of the Silver Colored Woman and that the Great Wisdom Discourse by Bodhisattva Nāgārjuna about women proved untrue. Bodhisattva Accumulated Wisdom and Śāriputra were so amazed to see the dragon daughter become a Buddha that they both were at a loss for words. A great crowd of gods and men who witnessed this realized that women and wicked people could attain Buddhahood, and delightedly put their palms together to worship the Buddha. This is entirely due to the virtue of the character “myō.”
There are 2,500 rivers in this world called Jambudvīpa: each river is as twisted as the minds of women, except the Shabaya River, which runs straight into the ocean in the west like a drawn rope. Like this river, the woman who believes in the Lotus Sūtra can go straight into the Pure Land to the West, thanks to the virtue of the character “myō.”
