Structural Analysis — Saju Interpretation
The Sin (辛) Day Master sits atop the Yu (酉) Earthly Branch. Based on the main qi of the Ilji (daily branch), the 10 God is Bigyeon (比肩), and the 12 Stages of Qi is Geonrok (建祿). Bigyeon is the star of the ego and subjectivity; the strength to stand on one’s own is supported by the Ilji. As it occupies the Geonrok position, it is a solid structure that relies on one’s own abilities to achieve independence.
In terms of Nabeum Five Elements, it belongs to Seokryumok (Pomegranate Wood), a classification frequently used in traditional Saju analysis to group pillars sharing the same Nabeum.
