The Stories of the Lotus Sutra, p171-172[A] central point of the story of Mahaprajapati and Yashodhara is related to the main doctrinal theme of the whole Sutra – universal salvation or the potential of all living beings to become a buddha. If, as many scholars believe, Chapter 12 with its story of the dragon princess was added to the Dharma Flower Sutra relatively late, this chapter would have been needed to make it quite clear that becoming a bodhisattva and eventually achieving full awakening is not something limited to men.
Not only Mahaprajapati and Yashodhara but Mahaprajapati’s six thousand nun followers as well, who are to become great Dharma teachers, gradually fulfilling the bodhisattva way, are assured of reaching supreme awakening as buddhas. In contrast with the story of the dragon princess, there is no mention of these nuns having to become male. Clearly, as Dharma teachers and bodhisattvas at least, they are female.
