Chapter 12 tells about the future becoming a buddha of Devadatta, the extremely evil one who rebelled against Shakyamuni, and the sudden awakening of an eight-year-old dragon girl. This chapter has been revered since ancient times as an expression of the awakening of evil people and women. While the esoteric Shingon school often uses the term “becoming a buddha in one’s present” it was first used when Zhanran, the sixth patriarch of the Chinese Tiantai school, interpreted chapter 12. The chapter may have been inserted into the Lotus Sutra later and does not form a natural part of the narrative line of the sutra as a whole. Yet, for the reason mentioned above, it is still revered and recited.
