Scholars point out that Jizang's Fahua xuanlun (Treatise on the Profundity of the Lotus Sutra) was referred to when Guanding compiled Zhiyi's lectures on the Lotus Sutra as a book. This paper takes up the parts of the Fahua xuanyi in which the Fahua xuanlun was referred to, considers the relation among Jizang's theory, Guanding's theory and Zhanran's annotation, and clarifies an aspect of Zhanran's understanding of Jizang's theory and Guanding's theory.
