Learn how the Day Pillar (일주) and Day Master (일간) in Korean Saju determine your core elemental identity and which lottery numbers naturally resonate with your personal birth energy.
In Korean Saju, the Four Pillars are the Year, Month, Day, and Hour columns — each encoded as a pair of Heavenly Stem and Earthly Branch. While all four pillars contribute to a person's elemental profile, the Day Pillar (일주, 日柱) holds a unique position: the Heavenly Stem of the Day Pillar, called the Day Master (일간, 日干), represents the core self. It is the pillar that Saju practitioners look at first, and the element of your Day Master has the most direct influence on which numbers resonate with your personal energy.
The Ten Heavenly Stems map directly to elements: 甲 and 乙 are Wood (甲 is Yang Wood, 乙 is Yin Wood), 丙 and 丁 are Fire (丙 Yang, 丁 Yin), 戊 and 己 are Earth (戊 Yang, 己 Yin), 庚 and 辛 are Metal (庚 Yang, 辛 Yin), 壬 and 癸 are Water (壬 Yang, 癸 Yin). Your Day Master is one of these ten stems, making your core element one of the five. In the Suri-Ohaeng system, this element directly determines which number endings carry the strongest resonance for you.
If your Day Master is 甲 or 乙 (Wood), your resonant numbers are those ending in 3 or 8. If your Day Master is 丙 or 丁 (Fire), your resonant numbers end in 2 or 7. 戊 or 己 (Earth) Day Masters resonate with numbers ending in 0 or 5. 庚 or 辛 (Metal) Day Masters resonate with 4 or 9 endings. 壬 or 癸 (Water) Day Masters resonate with 1 or 6 endings. This mapping is exact and does not vary — it is rooted in the Hetu numerology framework applied through the Day Master element.
