The present study is concerned with the hermeneutical continuity and differences of the Prajna-paramita thought in india, China, and Korea, focusing on Nagarjuna (150-250), Candrakirti (600-650), and Seungnang (450-550). Candrakfrti and Seungnang. Both Seungnang and Candrakirti use the method of dialectical reasoning to establish the middle way in the teachings of the Buddha. Although they have different historical backgrounds, as a Madhyamika they follow the central teaching of Nagarjuna. However, there are subtle differences between them in the following points. (a) In the context of doctrinal exposition, Seungnang seems to be closer to Nagarjuna than Candrakirti. (b) Candrakirti uses the formal logic in systematizing Nagarjuna`s teaching. On the other hand, Seungnang`s expositor Chi-tsang`s writing style follows the traditional Chinese style, such as muti-perspectival accounts of doctrine. (c) As for the reestablishment of saqviti, Seungnang seems to move up a step beyond Candrakirti. Seungnang gives more phenomenological direction for saqvrti, i.e., the unlimited interpretations of saqvrti and paramartha. This idea becomes a cornerstone for further development of Buddhist thought in the Far East.
