圓測對「一乘」概念的詮釋方法：以《解深密經疏．無自性相品》為中心=Woncheuk's Interpretation Method for the Concept of ＂Ekayāna＂: Focused on the Chapter ＂The Questions of Paramārthasamudgata＂ of Jieshenmi Jing Shu
This study highlights contemporary scholars' arguments on Woncheuk's (613-696) ＂Theory of Buddha Nature.＂ Such arguments stemmed from the viewpoint of the Lotus Sūtra quoted in Jieshenmi Jing Shu, which states that ＂in the ten directions of Buddha-land, the teaching of Ekayāna, two vehicles, three vehicles.＂ Some scholars interpreted this passage as ＂the two vehicles of Śrāvaka and Pratyekabuddha would transform into Mahāyāna and eventually achieve Buddhahood.＂ On this ground, they argued that Woncheuk agreed with the Ekayāna thought in the Lotus Sūtra. In other words, in his ＂Theory of Buddha Nature,＂ Woncheuk adopted the view that ＂all sentient beings can become buddhas.＂ However, scholars who held an alternate view argued that according to the position of Jieshenmi Jing Shu, this passage excerpted from the Lotus Sūtra should be understood as follows: ＂At the end of the path of Buddhist practice, the two vehicles cannot achieve Buddhahood.＂ They contended that Woncheuk still adopted the viewpoint of ＂distinction in five natures (pañcagotra).＂ This study demonstrates the following: despite the tension between two contradictory forms of inheritance, the exegesis or interpretation strategy Woncheuk adopted regarding his Theory of Buddha Nature would indirectly reflect his own position. Finally, the author explains that the interpretation strategy that Woncheuk adopted alluded to the ＂theory of three bodies＂ and reinterpreted the verse of ＂neither two nor three Dharmas＂ in the Lotus Sūtra, whereby this verse did not imply the stance of ＂all beings become buddhas＂ in the ＂Theory of Buddha Nature.＂
