Reading the Structure — Saju Interpretation
The Gye (癸) Day Master sits atop the Yu (酉) Earthly Branch. Based on the main Qi of the Ilji (Day Branch), the 10 God is Pyeonin (偏印), and the 12 Stages of Life is Byeong (病). Pyeonin is the star of intuition and special talents—unique ideas and professional expertise grow from the Day Branch. Because it sits in the stage of ‘Sickness’ (Byeong), it is a structure that deepens sensitivity and empathy.
In terms of Nabeum, it belongs to Geombong-geum (Sword-tip Metal), a classification often used in traditional Saju studies to group pillars sharing the same phonetic element.
