What is Saju (Four Pillars)?
Think of Saju Palza (四柱八字) as a cosmic snapshot of the moment you were born. The name means "four pillars, eight characters"—your year, month, day, and hour of birth become four pillars, and each pillar contains two parts: a Heavenly Stem and an Earthly Branch. That gives us eight characters total, like a personal cosmic fingerprint that reveals your personality, talents, and how fortune flows through your life.
The Structure: Four Pillars
| Pillar | Meaning | What It Reveals |
| Year Pillar | Birth year | Your roots, childhood patterns |
| Month Pillar | Birth month | Family dynamics, youth energy, pattern foundation |
| Day Pillar | Birth day | Your core self, relationships, identity |
| Hour Pillar | Birth hour | Later life, legacy, children |
Each pillar splits into two parts: the Heavenly Stem sits on top, the Earthly Branch below. Four pillars, two characters each—that's where "eight characters" comes from.
Heavenly Stems and Earthly Branches
10 Heavenly Stems: Gap, Eul, Byeong, Jeong, Mu, Gi, Gyeong, Shin, Im, Gye (甲乙丙丁戊己庚辛壬癸)
12 Earthly Branches: Ja, Chuk, In, Myo, Jin, Sa, O, Mi, Shin, Yu, Sul, Hae (子丑寅卯辰巳午未申酉戌亥)
The Heavenly Stems carry heaven's energy, while Earthly Branches ground us with earth's force. When you combine these, you get 60 unique pairings—the famous Sexagenary Cycle that resets every 60 years. Ever heard of someone's "60th birthday celebration"? That's when the cycle completes and returns to their birth combination.
Understanding Structure Through Celebrities
IU (Lee Ji-eun, born May 16, 1993) carries Jeong Fire (丁火) as her Day Master. Picture a candle flame or a warm lantern—that's Jeong Fire. It's gentle but persistent, intimate rather than blazing. You can hear this in IU's music: that delicate sensitivity, the way she comforts listeners with warmth rather than overwhelming them. It's all right there in her chart.
Your Day Master (日干) is you—the main character in your Saju story. Everything else in your eight characters plays off this central element, creating the unique dynamic that makes you who you are.
Saju and Fortune (運)
Here's the key distinction: your Saju is fixed "destiny (命)" set at birth, but your "fortune (運)" keeps moving. Major Fortune shifts every 10 years, Annual Fortune changes yearly, and Monthly Fortune flows month by month. How these moving cycles interact with your fixed Saju determines whether times feel smooth or challenging.
Even a powerful Saju can hit rough patches when fortune cycles turn unfavorable. And someone with an ordinary chart can accomplish extraordinary things when fortune aligns just right. Meongri studies explore exactly this dance between what's given and what's unfolding.
