Ding Fire Day Master (丁火)
Ding is yin Fire: not the sun but the candle, the lamp, the star at night. Its light is smaller, closer and more personal.
Personality
Ding people are warm on the inside, attentive and quietly persistent. They light up the people close to them rather than the whole stage.
Strengths
- Thoughtful, caring and loyal
- Focus and inner conviction
- Keeps going steadily even when conditions are poor
Things to watch
- Can worry or brood
- Tends to hold feelings in
- Flickers in strong wind — needs a stable source of 'fuel' (support, learning)
What helps a Ding Fire chart
Ding relies on wood (especially Jia) as fuel; with good support it does well even in autumn and winter.
Classical imagery
丁火柔中,内性昭融。旺而不烈,衰而不穷。“Ding Fire is gentle at its core, its nature inwardly bright. Strong, it is never harsh; weak, it is never spent.” Read: modest light that lasts. — Di Tian Sui (滴天髓), “On the Heavenly Stems”; translation and gloss are our own.
A Day Master is only the starting point: two people with the same Day Master can read very differently depending on their birth month and the other seven characters in the chart.
