Geng Metal Chapter · Di Tian Sui and Fate Analysis

1. Di Tian Sui Original Text

Geng Metal carries Sha; firmness and vigor are supreme.
With water it becomes clear, with fire it becomes sharp.
Moist earth yields growth, dry earth becomes brittle.
It can overpower Jia Wood, but loses to Yi Wood.

2. Original Annotations

Original note: Geng Metal is the Taibai of the heavens, bearing Sha and being firm and vigorous.
When tempered by water, its qi flows clear; when tempered by fire, its qi is pure and sharp.
Earth with water can sustain its life; earth with fire makes it brittle.
Jia Wood may be strong, able to strike it down; Yi Wood though soft, when allied becomes weak.

3. Ren's Yi Book Explanation

Ren's Yi Book: Geng is the autumnal, austere qi; firmness is the pinnacle.
Those who obtain water to become clear are Ren Water; Ren Water arises, channels the nature of rigidity and killing, thus feeling tempered and crystalline.
Those who obtain fire to become sharp are Ding Fire; Ding Fire is yin and gentle, does not oppose Geng Metal; well-smelted and refined, it forms swords and halberds; in the great furnace tempered, the edge is sometimes revealed on the anvil.

Born in spring and summer, its qi is somewhat weak; when it encounters the damp earth of Chou and Chen, it grows; when it encounters the dry earth of Wei and Xu, it becomes brittle.
Jia Wood is a true foe; its strength can vanquish it; allied with Yi it seems to have sentiment.
Yi is not completely allied with Geng to aid aggression; Geng is not completely allied with Yi to become weak; this requires careful discernment.

4. Modern Fate Analysis

Geng Metal with Sha, firmness is paramount.

Geng Metal is Yang Metal, symbolizing knives, swords, axes, and mineral metal; its nature is fierce and decisive, carrying the power of sternness and execution, most capable of breakthroughs and resolution.

With water to become clear:
Water can refine the impurities of Geng Metal, making its sharp edge inwardly restrained and not muddy; there is clarity within firmness, majesty without brutality.

With fire to become sharp:
Fire is the forging to make it. It can make Geng Metal into tools and blades.
Ding Fire is especially good; tempering the hard with a soft fire, beneficial without destroying.

Moist soil yields life, dry soil yields brittleness:
Wet soil hides metal, can nourish its body; dry soil, when it sees metal, makes it brittle. Therefore Geng Metal dislikes dry and arid soil.

Can overpower Jia Wood, but loses to Yi Wood:
Geng Metal against Jia Wood is a proper克; hard over hard, its power can vanquish it; against Yi Wood, hardness and softness blend, and it easily forms attachment; if not restrained, it will damage its hard and vigorous foundation.

In summary, the use of Geng Metal lies in its "refining."
Water to purify, Fire to forge, Earth to nourish; only then can it transform killing into power, and hardness into a tool.
