Geng Shen Day Pillar 庚申
Sharp forged steel
What does the Geng Shen Day Pillar mean?
The Day Pillar is the two characters of the day you were born: a Heavenly Stem on top (your Day Master, the “you” of a Saju chart) and an Earthly Branch below (your inner self and spouse palace). In Geng Shen (庚申), the Day Master is Geng Metal (a well-forged blade of steel) sitting on the Monkey branch, whose element is Metal.
You sit on your own roots (Prosperity), with very strong decisiveness and drive. Loyal, definite in what you take and drop, and your direct expression means a gentler tone is a blessing.
Geng Shen personality: the Geng Metal Day Master
Geng Metal is strong and decisive like a well-forged blade. You have a clear sense of right and wrong, value principle, and are definite about what you accept and reject, so people find you trustworthy. You shine in a crisis with a fighter’s spirit and drive toward your goals. Your expression can feel stiff, so a softer tone helps relationships.
What makes Geng Shen different from the other five Geng Metal Day Pillars is the branch it sits on, covered below.
The Monkey seat: your inner self
With Shen beneath your Day Master, you are realistic, witty and good at solving problems. There is sharp Metal energy in your spouse seat, so you are drawn to capable, no-nonsense people. So you don’t lose feeling while weighing efficiency, spend time on “emotional conversation” too.
Geng Shen in love and marriage
The Friend energy, like you, sits in your spouse seat, so you feel comfortable in an equal, friend-like relationship. You understand each other because you are equals, but a tug-of-war over who leads can arise.
Geng Metal loves loyally and clearly. You are definite and wholehearted, but your directness can hurt. Keep in mind that a kind word protects love better than a correct one.
Friend here means: Friend (Bi Jian) stands for an equal: a colleague, sibling or rival. Strongly independent, you have a clear will to do things yourself rather than lean on others, and with a definite point of view you are not easily shaken. You create synergy when you meet colleagues to work with, but you may be called stubborn, so respecting the other person’s opinion helps in collaboration.
Energy and life stage
Prosperity (Jian Lu): a stable energy of standing on your own strength. Good independence and drive, with a strong power to earn and stand by yourself.
Hidden inside the Monkey branch: Wu (Earth, 7 days), Ren (Water, 7 days), Geng (Metal, 16 days). These quieter energies show up in private, under stress or later in life.
Health tendencies of Metal Day Masters
Areas to look after: lungs, large intestine, bronchi, skin and nose.
Too much Metal energy dries the airways and skin, and feelings can turn dry and edgy. Fluids, humidity, soft food and warm conversation restore balance.
Too little Metal energy leaves bronchi and skin weak and prone to colds in changing seasons. Look after breathing exercises, clean air and regular bowel habits.
Geng Shen compatibility
- Six Harmony: the Monkey pairs with the Snake. People with a Snake Day Branch often feel an easy pull toward you.
- Three Harmony: the Rat · Dragon · Monkey form a Water team, so those animals tend to bring out your best.
- Clash: the Monkey clashes with the Tiger. It is not doom, only a spot where friction and change come easily.
- Perfect match on stem and branch: Yi Si (乙巳) combines with Geng Shen on both the stem and the branch.
- Opposite pillar (most friction): Bing Yin (丙寅): its stem is Seven Killings to you and its branch clashes with yours.
