Being the earliest of existing annotations of Zhao Lun, Huida’s Commentary on Zhao Lun hasn’t been fully valued academically. There are not many studies on the thought of Huida’s book, almost blank. However, among the few existing philosophical texts in the Southern dynasty, Commentary on Zhao Lun should attract more attention to filling the gap of philosophical history. This article discusses Prajñā in Huida’s Commentary on Zhao Lun, pointing out how Huida builds his own discourse system based on ti-Prajñā and yong-Prajñā. He centralizes the idea of tiPrajñā, emphasizing that there is no differentiation between subjects and objects. With this thought, ti-Prajñā covers the concept of yong-Prajñā and satya-dvaya. He uniquely brings the realm of heart's non-attainment to interpret the idea of Prajñā. The Prajñā of essence-function (ti-yong) is the key concept throughout Huida’s Commentary on Zhao Lun, and reveals Huida's self-contained and unique system of thought.
