About DukStack
Understanding your destiny through the lens of tradition and technology
Traditional Wisdom Meets Modern AI
DukStack bridges centuries of East Asian metaphysical tradition with the power of modern artificial intelligence. Saju (Four Pillars of Destiny) is one of the oldest and most respected systems of personal fortune analysis in Korean culture, dating back over a thousand years to its roots in Chinese cosmology.
The system maps the cosmic energies present at the exact moment of your birth into four pillars, each consisting of a Heavenly Stem (Cheongan) and an Earthly Branch (Jiji). Together, these eight characters form your birth chart, a blueprint of the elemental forces that shape your personality, relationships, career, and life path.
At DukStack, we honor this tradition while making it accessible to a modern, global audience. Our engine performs precise astronomical and calendrical calculations to derive your Four Pillars, then leverages advanced AI to interpret the results with nuance and depth that goes beyond simple lookup tables.
Our Methodology
A truly comprehensive Four Pillars reading goes far beyond identifying your eight characters. The interactions between them reveal the dynamic forces at work in your life. DukStack's analysis engine detects all nine major types of elemental interactions:
Heavenly Stem Combination (Cheongan Hap)
When specific pairs of Heavenly Stems combine, they transform and create new elemental energy.
Heavenly Stem Clash (Cheongan Chung)
Opposing stems create tension and conflict, indicating areas of challenge and growth.
Earthly Branch Six Harmony (Yughap)
Six pairs of branches naturally harmonize, bringing cooperation and mutual support.
Earthly Branch Three Harmony (Samhap)
Three branches unite to form a powerful elemental frame, amplifying specific energies.
Earthly Branch Seasonal Harmony (Banghap)
Branches sharing the same season combine to reinforce their seasonal element.
Earthly Branch Clash (Jiji Chung)
Opposing branches create friction, signaling change, disruption, or transformation.
Earthly Branch Harm (Jiji Hae)
Harmful relationships between branches indicate hidden conflicts and vulnerabilities.
Earthly Branch Destruction (Jiji Pa)
Destructive interactions break apart existing structures, sometimes clearing the way for renewal.
Earthly Branch Penalty (Jiji Hyeong)
Penalty relationships represent karmic lessons and deep-seated patterns requiring awareness.
Beyond interactions, DukStack calculates your Five Element balance (Wood, Fire, Earth, Metal, Water) and determines which elements are favorable (yongsin) and unfavorable (gisin) for you. This assessment informs personalized guidance across all areas of your reading.
All of these structural insights are then synthesized by our AI, which generates a cohesive, personalized interpretation covering personality, career, relationships, health, and your outlook for the current year.
