Beyond the elements and the Ten Gods, saju has a subtler tool: the Twelve Life Stages. It traces how a single energy — above all your Day Master, the self — grows strong and then fades as it passes through the twelve branches, drawing it as one life cycle of birth and growth, peak and decline, death and renewal. It is rather like watching a single element live through the four seasons.
The rising arc begins like this. Conception is the seed held within the mother; Nurture is that seed being fed and taking form. Then Birth is the freshly born stage, green and full of promise; Bath is the still-unstable, wavering early time; and Coming-of-Age is the threshold of adulthood, gaining shape and learning to stand alone.
The peak comes next. Establishment is the stage of maturity, standing tall on one’s own strength; and the Peak is the very zenith of the energy — the top of this cycle, a place brimming with strength and influence.
Then comes the descending arc. Decline is the mellowing just past the peak; Illness is the stage of weakening; Death is when the energy is spent — not a literal death but the exhaustion of one cycle. Tomb is the place of gathering and storing, a rest; and Extinction is the lowest, emptied point, just before a seed forms again. And the cycle turns back to Conception.
Here is how it is read. Which branch the Day Master sits in, and so which stage it falls into, gently suggests how naturally strong and supported that energy is; and each pillar’s stage colours that area and season of life. Yet, as with everything, this is a tendency and a season — a stage of “Death” or “Extinction” is not bad but a rest and an emptying before renewal. As always in FortuneLeaf, this is offered for reflection rather than as a fixed fate — a way to consider, kindly, which season your own energy is passing through now.
