From Basics to Advanced Eastern Fortune Analysis
Saju (四柱) means 'Four Pillars' — the Year Pillar, Month Pillar, Day Pillar, and Hour Pillar of your birth. Each pillar consists of two characters: a Heavenly Stem (Cheongan) and an Earthly Branch (Jiji), totaling eight characters. This is why it's called 'Saju Palja' (四柱八字, Four Pillars Eight Characters). These eight characters represent the cosmic energy configuration at the moment of birth and are used to interpret a person's innate personality, talents, and life trajectory.
The history of Saju dates back to Li Xuzhong of China's Tang Dynasty (618–907), and was refined by Xu Ziping of the Song Dynasty into the Day Master-centered system used today. In Korea, Saju has been consulted since the Joseon Dynasty for civil service examinations, marriages, and naming children. Even today, Koreans commonly check their fortune for the New Year, verify romantic compatibility, and choose auspicious dates for moving.
K-SAJU reinterprets this traditional analysis as an RPG character sheet, making it easy and fun for anyone to explore their personal Saju. While preserving the depth of traditional interpretation, results are presented through intuitive stat bars and element charts.
The Five Elements are Wood (木), Fire (火), Earth (土), Metal (金), and Water (水). All phenomena in nature are explained through the harmony and transformation of these five energies. In Saju analysis, the balance of these elements is the key factor determining one's destiny.
The energy of growth, expansion, and creation. Symbolizing spring, people strong in Wood are ambitious, creative, and possess natural leadership. When excessive, they can be stubborn; when deficient, indecisive. Direction: East. Color: Blue/Green.
The energy of passion, brightness, and transformation. Representing summer, those strong in Fire are outgoing, sociable, and eloquent. In excess, they become impulsive and emotional; when lacking, passive and withdrawn. Direction: South. Color: Red.
The energy of stability, mediation, and nurturing. Associated with transitional seasons, those strong in Earth are reliable, broad-minded, and pragmatic. Too much leads to stubbornness; too little brings instability. Direction: Center. Color: Yellow.
The energy of determination, justice, and precision. Symbolizing autumn, those strong in Metal are decisive, principled, and analytically sharp. In excess, they become cold and critical; when deficient, they lack resolve. Direction: West. Color: White.
The energy of wisdom, flexibility, and communication. Representing winter, those strong in Water are intelligent, adaptable, and insightful. Too much leads to melancholy and pessimism; too little creates rigidity. Direction: North. Color: Black.
The Generating Cycle (Sangsaeng, 相生) represents mutual support: Wood → Fire → Earth → Metal → Water → Wood. Wood feeds Fire, Fire creates ash (Earth), Earth yields Metal ore, Metal surfaces condense Water, and Water nourishes Wood.
The Overcoming Cycle (Sanggeuk, 相剋) represents mutual restraint: Wood → Earth → Water → Fire → Metal → Wood. Wood drains Earth's nutrients, Earth dams Water, Water extinguishes Fire, Fire melts Metal, and Metal cuts Wood. Overcoming is not purely negative — it's an essential force for maintaining balance.
The 10 Heavenly Stems represent celestial energy, while the 12 Earthly Branches represent terrestrial energy. Their combinations form the basic units of Saju.
Gap (甲·Yang Wood), Eul (乙·Yin Wood), Byeong (丙·Yang Fire), Jeong (丁·Yin Fire), Mu (戊·Yang Earth), Gi (己·Yin Earth), Gyeong (庚·Yang Metal), Sin (辛·Yin Metal), Im (壬·Yang Water), Gye (癸·Yin Water)
Heavenly Stems represent energy descending from the sky — outwardly visible personality and behavioral patterns. Yang Stems (甲丙戊庚壬) are active and assertive, while Yin Stems (乙丁己辛癸) are delicate and receptive.
Ja (子·Rat), Chuk (丑·Ox), In (寅·Tiger), Myo (卯·Rabbit), Jin (辰·Dragon), Sa (巳·Snake), O (午·Horse), Mi (未·Goat), Sin (申·Monkey), Yu (酉·Rooster), Sul (戌·Dog), Hae (亥·Pig)
Earthly Branches represent energy rising from the ground — inner emotions and latent characteristics. Each branch is linked to one of 12 animals (the zodiac origin), and also corresponds to seasons and time periods.
A Saju chart consists of four pillars (Year, Month, Day, Hour), each with a top character (Heavenly Stem) and bottom character (Earthly Branch).
The Day Master is the Heavenly Stem of your birth day — the most important character representing 'you' in Saju. Your base personality is determined by the Day Master's element and yin-yang quality. The relationships between the Day Master and the other seven characters reveal talents, career aptitude, health, and interpersonal dynamics.
The Ten Gods classify each character's relationship to the Day Master. Bigyeop (比劫) represents siblings and competitors, Siksang (食傷) represents expression and creativity, Jaeseong (財星) represents wealth and father, Gwanseong (官星) represents career and husband, and Inseong (印星) represents knowledge and mother. K-SAJU converts these distributions into five stats: Self-Esteem, Creativity, Wealth, Leadership, and Wisdom.
Daeun represents the overarching fortune that shifts every 10 years. Calculated from the Month Pillar in either forward or reverse progression, each Daeun period brings a new Stem-Branch combination. How this combination's elements interact with your Day Master determines the general energy of that decade.
For example, if your Day Master is Wood and a Water Daeun arrives, it's like rain nourishing a tree — a period of growth and development. Conversely, a Metal Daeun may bring challenges, as Metal cuts Wood. K-SAJU's result page visually displays your 10-year Daeun timeline so you can see these shifts at a glance.
Saju doesn't declare a fixed destiny. It operates on the principle that 'knowledge is power' — a tool for self-understanding to maximize innate strengths and address weaknesses. In modern Korea, people consult Saju for confidence before job interviews, to playfully check romantic compatibility, and to time important decisions.
Psychologist Carl Jung expressed interest in Eastern fortune systems and attempted to explain them through his concept of synchronicity. While Saju is not scientifically proven, it holds unique value as a crystallization of thousands of years of human observation across East Asian cultures. K-SAJU transforms this tradition into a gamified modern experience accessible to everyone.
