A Study on the Interpretive Application (通辯) on the basis of the Transformative Principles (通變) of Yujeong (有情) and Mujeong (無情) in Japingjinjeon

The purpose This study aims to examine the concepts of Yujeong (有情) and Mujeong (無情) as presented in Japingjinjeon (『自評眞詮』), and to explore how the principle of Tongbyeon (通變) can be effectively applied to interpret (Tongbyeon, 通辯) Four Pillars charts. To this end, the definitions of Yujeong/Mujeong and Tongbyeon in both its theoretical (通變) and practical (通辯) dimensions are discussed. Representative principles of Tongbyeon from Japingjinjeon are reviewed, followed by an analysis of charts exemplifying Yujeong and Mujeong characteristics from both interpretive perspectives. The analysis reveals that the first Yujeong case, characterized by a “Harmony of Hurting Officer and Preserved Officer” (合傷存官), suggests a balance of creativity and discipline, with potential for prosperity in education, planning, and writing. The second case, a Wealth Structure, shows that the interaction between resource-disrupting elements (Bi/Geob) and the Seven Killings results in a balanced leadership model, avoiding structural breakdown and suggesting stable growth with access to wealth and authority. Conversely, the first Mujeong case, involving a “Greed for Wealth Damaging Seal” (貪財壞印) structure, indicates potential for material success but a lack of inner stability and insight, requiring strategic judgment based on value-oriented decision-making. The second case, based on a Hurting Officer structure, supports success in fields valuing independence and creativity over organizational conformity. The findings suggest that effective interpretation (Tongbyeon, 通辯) depends on how the dynamics of a chart are read and applied within a given personal context. Ultimately, applying the principle of Tongbyeon (通變) with situational awareness is essential for accurate and meaningful interpretation.
