Know Your Fate, See Your Fortune
命
Ming · Fate
Innate talents and conditions
Like a sports car, family car, or tractor — each has its own characteristics.
運
Yun · Fortune
Changes in timing and environment
Like highways, mountain roads, or muddy paths — varies with circumstances.
Your Saju consists of innate fate (命) and flowing fortune (運). Fate cannot be changed, but by understanding the flow of fortune, you can advance during favorable times and prepare during challenging ones. 1Fate helps you deeply understand yourself.
Continuing Korea's Tradition
The founding ideal of the Korean Peninsula, Hongik Ingan, emphasizes harmony between heaven, earth, and humanity. This philosophy and the perspective of Yin-Yang and Five Elements became the foundation of Korean Peninsula culture, and the tradition of exploring nature's principles continues to this day. After Neo-Confucianism arrived in the late Goryeo period, Korea refined it into an academic system, maintaining the tradition of Four Pillars interpretation for a long time. King Sejong's creation of the Korean alphabet and the adoption of traditional symbols in the 19th century are examples of traditional philosophy being established as a social foundation. 1Fate reconstructs this long-standing insight in modern language and makes it accessible to everyone.
