Abstract

In Fahuawenju, Zhiyi uses the Threefold Buddha Nature when annotating the meaning of the Lotus Sutra. In eleven chapters of the Lotus Sutra, the usage of the Threefold Buddha Nature appears. According to the contextual meaning of the Lotus Sutra, Zhengyin [正因], Liaoyin [了因], and Yuanyin [緣因] are used separately or together as one. Thus, this paper classifies the usage of the Threefold Buddha Nature in Chapter Two of Fahuawenju. The usage of the Threefold Buddha Nature in Chapter Two of Fahuawenju is categorized in five depending on the contextual meaning. The first and the second usages emphasized the perfect causes [圓因] and the cause [因] in general meaning. The third usage emphasizes the causes and results [因果]. The fourth and the fifth usages emphasized the essence [體] of the true aspects of the Middle Way. Based upon this analysis of the Threefold Buddha Nature, Chapter Three of this paper demonstrates that the essence of the Buddha Nature as Zhengyin contains the meaning of the Middle Way. Tiantai Zhiyi interpretes the Three Truths Verses [三諦偈] in Nagarjuna‘s The Treatise on the Middle Way [『中論』] with the four teachings [藏通別圓] to demonstrate that The Treatise on the Middle contains the truth of Emptiness [空], Nominal designation [假] and Middle [中]. This paper explicates, with the analysis of the usage of Threefold Buddha Nature, that Tiantai Zhiyi regards the essence of the Buddha Nature as Zhengyin and the Threefold Buddha Nature as the True Nature of the Middle Way [中道實相].
