Di Tian Sui 滴天髓
the poetic core
What it is
The tradition's most quoted and most argued-over text: a set of terse, image-dense verses on how qi behaves in a chart — strength, flow, obedience and rebellion, the natures of the ten stems. Traditionally attributed to a Song author and popularised with Ming-era prestige (the name of Liu Bowen attaches to it in tradition), it reached its modern form through Qing commentaries — most influentially Ren Tieqiao's, whose case-annotated edition is how most readers now meet it.
What's in it
Almost no procedure — that's the other texts' job — and almost pure judgment: what a healthy chart is (qi that flows), what strength really means (support that arrives where it's needed), when to follow a dominant force rather than fight it (the doctrine behind the special structures), and the famous stem verses this site's glossary echoes (甲 the towering timber, 乙 the vine…).
One famous idea
何知其人富，财气通门户 — "How do you know a person is wealthy? The wealth-qi connects to the gate." Wealth in a chart is not the presence of wealth stars but their connection — rooted, protected, flowing to the Day Master. Dose and flow over labels: the entire Di Tian Sui attitude in one line.
How to read it today
Slowly, with commentary, after the foundations — it is the text that rewards the most experience and misleads the most beginners, because every verse states a conclusion whose conditions live in the commentary. It is also where lineages differ most sharply in interpretation; the version of these judgments taught at Yixin Academy follows the Wei Qianli line's readings.

"Dripping Heaven's Essence" — the marrow of celestial pattern, drop by drop; a Qing-era favourite title for distilled doctrine.
Is Di Tian Sui good for beginners?
Honestly, no — foundations first. It's the deep-end text: every verse is a conclusion whose conditions live in the commentary, which rewards experience and misleads beginners.
