What is Twelve Stages (Sibi Unseong Life Phases)?
The Sibi Unseong system — Jangsaeng (Long Birth), Mogyok (Bathing), Gwandae (Crown Wearing), Geonrok (Prosperity), Jewang (Monarch), Soe (Decline), Byeong (Sickness), Sa (Death), Myo (Tomb), Jeol (Severance), Tae (Conception), Yang (Nurture) — tracks the life cycle of vital energy as it rotates through the Earthly Branches. A Heavenly Stem placed in Jewang (Monarch, strongest) is vigorous and prosperous; in Sa (Death), it is powerless; in Tae (Conception), it holds latent potential not yet manifest. The stage is calculated by finding the relationship between a stem's element and its position relative to its ruling branch. Unlike Vedic Baladi Avastha (which uses a similar framework), Sibi Unseong mechanics are distinct, making each system's interpretation of a planet's vitality unique.
