The story about how can the daughter of Nāga become a Buddha from women into a man, was very famous and detail in all our families. In the Mahāyana Sūtra called “Saddharma Pundarīka Sūtra (Lotus Sutra)”, ?āriputra had thought that all women were dirty, so all women were not the candidates of yogacārins and also could not get the highest enlightenment. He also said that all women had the five restrictions, therefore, all women could not become Buddhas from the states of female. Meanwhile, the daughter of Nāga became a man immediately, then she or he went forward to the Pure World in the South India, sat on the beautiful lotus flower and become a Buddha. From the stories of the daughter of Nāga become a Buddha, we also find out the two important point. Finally, to become a Buddha, we don’t need to become a man first, because woman can also become a Buddha. Therefore, it breaks out the difference between man and woman. Secondly, to become a Buddha, We don’t need to bear in the Jambūdvīpa of Central India, we can also become a Buddha in Sāhvaya Jambūdvīpa of South India. Therefore, it breaks out the traditional ideas of Buddha Centralism in Ga?ga of the Sthavira. Throughout the discussion about how can the daughter of Nāga become a Buddha from a women into a man in Saddharma Pu?darīka Sūtra, I want to show up the different manner about this two question in the Sūtra.
