Abstract: As a temporal proposition borrowed from Buddhism,the three periods are emptyplays a foundational role in the Chongxuan school by demonstrating and elucidating how the Celestial Venerable of the Primordial and all sentient beings attain the Chongxuan Dao. Through an analysis of the Xuanzhu Lu,semantic analysis shows that the “three periods” refer to the three temporal phases—past,present, and future—in which all phenomena manifest,while “empty” signifies the non-substantiality,nameable,and conditionally dependent nature of the Dao as ontological reality.Doctrinally, the “three periods are empty” implies that all consciousness and phenomena inherently possess the temporal phase structure of past,present,and future,while their ontological Dao lies in non-substantiality,nameable, and conditioned nature.Theoretically,the proposition “the three periods are empty” clearly evidences the ontological essence of the Chongxuan Dao and thoroughly establishes the ultimate possibility and reality of attaining it.This not only reveals the philosophical dimension of “comprehending the profound principles of the Dao” in Chongxuan Daoism but also opens up the religious dimension of “the technique of attaining the Dao and immortality”.
