Fate vs. Function

In modern Korea, it's common to ask both "What is your MBTI?" and "What is your Saju (Four Pillars)?" But these two systems represent fundamentally different worldviews.

The Determinism of Saju

Saju (Four Pillars of Destiny) is based on the exact time of your birth. It posits that the alignment of cosmic energy (Qi) at your first breath determines your path.

• Root: Chinese Metaphysics / Taoism.
• Philosophy: You are part of nature's cycle. Your "fate" is the weather; you cannot change the weather, but you can carry an umbrella.

The Agency of MBTI

MBTI (Myers-Briggs) is based on cognitive preferences. It posits that your personality is defined by how you prefer to process information.

• Root: Western Psychology (Carl Jung).
• Philosophy: You are an individual agent. By understanding your "tools" (cognitive functions), you can optimize your life.

Where they meet

Interestingly, both systems categorize humans into archetypes to help us understand ourselves.

• Day Master (Saju) ≈ Dominant Function (MBTI): Your core self.
• Five Elements Balance ≈ Fe/Ti Balance: Seeking harmony.

Conclusion

Whether you believe in the stars or psychology, both tools serve the same purpose: Self-Objectification. Stepping outside yourself to view your traits objectively is the first step to growth.
