In addition, there is controversy as to whether the description in the Lotus Sutra means Buddhahood after changing into a man or Buddhahood just as a woman who she is, and whether the dragon should be regarded as the dragon god classified in Tenbu (deities who resides in the heavenly realm, one of six realms in which the souls of living beings transmigrate from one to another), in terms of Rokudo (six realms of reincarnation) or Jikkai (ten spiritual realms), or as an animal inferior to human beings.
なお、この記述が変成男子で成仏したか、女人身そのままの成仏か、あるいは竜を六道や十界の観点から天部に位置する竜神と見るか、それとも人間より劣る畜生と見るかなどの議論がある。
