How the principle of Yin (음) and Yang (양) creates balance and meaning in your Saju birth chart.
At the foundation of Korean Saju lies the ancient principle of Yin (음, eum) and Yang (양, yang) — the cosmic dance of opposing yet complementary forces that creates all existence. Before there were Five Elements, before there were Heavenly Stems and Earthly Branches, there was the primal division of universal energy into these two fundamental polarities.
Yang represents the active, bright, warm, expanding, and masculine principle. Yin represents the receptive, dark, cool, contracting, and feminine principle. In Korean philosophy, neither is superior to the other — they are equal partners in an eternal dance. Every Yang contains the seed of Yin, and every Yin contains the seed of Yang, as beautifully illustrated in the Taeguk (태극) symbol that graces the Korean national flag.
In your Saju chart, every Heavenly Stem is either Yin or Yang. The ten stems alternate: 甲 (Yang Wood), 乙 (Yin Wood), 丙 (Yang Fire), 丁 (Yin Fire), 戊 (Yang Earth), 己 (Yin Earth), 庚 (Yang Metal), 辛 (Yin Metal), 壬 (Yang Water), 癸 (Yin Water). Similarly, the twelve Earthly Branches alternate between Yin and Yang, creating a complex interplay of energies across your four pillars.
