In Saju Myeongrihak (Four Pillars of Destiny), the 12 Unseong (12 Stages of Fortune) is a theory that observes the strength and decline of energy by dividing it into twelve stages. It measures how the energy of the Cheongan (Heavenly Stems) fluctuates when it encounters the environment of the Jiji (Earthly Branches). To put it simply, it maps the flow of energy to the human life cycle—birth, growth, reaching a peak, aging, illness, death, and eventual reincarnation. Rather than just labeling luck as "good" or "bad," it serves as a nuanced indicator of whether your current energy is at its seasonal peak or in a period of rest.
The first stages where energy begins to rise are Jangseng, Mok-yok, and Gwandae. Jangseng represents a vibrant period, much like a newborn baby, characterized by purity and receiving plenty of support from those around you. Mok-yok signifies a curious and provocative energy, similar to a child washing and dressing up to show themselves off to the world. Finally, Gwandae symbolizes the bold energy of entering young adulthood, where one puts on formal attire and prepares to step out into society. Generally, these stages are characterized by an upward trajectory of energy that expands outward.
The stages where energy reaches its peak are Geon-rok, Je-wang, and Soe. Geon-rok represents a completed level of expertise, strong enough to establish one's own family lineage or legacy through independent strength, while Je-wang symbolizes the most powerful force at its zenith, commanding the world from the very top. However, just as the moon begins to wane once it is full, after the peak of Je-wang comes the stage of Soe. While Soe may still appear powerful on the outside, it is a period of internalizing seasoned maturity and preparing the wisdom of retreat. It can be described as an energy akin to a sophisticated, veteran manager of life.
The ensuing stages are Byeong, Sa, and Myo, which represent the process of energy declining and coming to a halt. Byeong is a period where physical activity decreases and one sinks into their inner self, while Sa refers to a state of suspended energy that is well-suited for exercising high levels of concentration and spiritual power. Myo is the stage of storing and finishing energy by putting it into a warehouse, characterized by an excellent ability to secure practical interests and preserve resources. Rather than physical dynamism, these stages exert great strength in mental and static realms.
Finally, there are the stages of Jeol, Tae, and Yang. Jeol represents a state where all previous energies are severed and have returned to nothingness (void); while it appears the most unstable, it possesses an explosive potential right before birthing a new beginning. Tae signifies a hopeful start as life is conceived once again, and Yang refers to a preparatory period of growing while being safely protected within the mother's womb.
Through the 12 Unseong, we can determine how to utilize our energy by observing whether a specific character in our Saju occupies the "Je-wang" (Imperial Peak) position or the "Jeol" (Severance) position. For instance, if the Wealth Star (Jaeseong) is situated in the Je-wang stage, one can boldly pursue business expansion; however, if it resides in the Myo (Grave) stage, one should focus on defending and managing existing assets. For a more concrete example, if your Expression Star (Siksang), which represents your creativity and output, is in the Jangseng stage, you can produce fresh and innovative ideas with the support of a strong nurturing environment. Conversely, if it is in the Sa (Death) stage, rather than outward flamboyance, you may find profound success in specialized research or highly technical fields that require deep, concentrated mental focus. As such, the 12 Unseong provides crucial insights for analyzing the multifaceted nature of human life.
