Seasonal Balance — the Climate Layer
In Lesson 7 we chose the Useful God by four methods, and the climate method was the thinnest of them — only “winter needs warming, summer needs cooling”. This lesson goes back to the source: the Zi Ping Zhen Quan chapter On the Useful God and Climate (論用神配氣候得失), and the month-by-month climate table of the Qiong Tong Bao Jian (窮通寶鑑), the book that lists, for each of the ten Day Masters in each of the twelve months, exactly what the chart needs. Climate is a layer of its own: it does not decide whether a Pattern forms, or how high it stands — it decides whether the chart can breathe in the season it was born into.
The classic's chapter: when climate overrules the rules
The chapter opens with the sentence that frames everything: “In reading a chart, the month command's Useful God is the master — but it must also be matched against the climate. A hero born in his season succeeds with half the effort; born out of season, even rare talent struggles.” The commentator Xu adds the working rule: the Useful God must ride the season, “summer linen, winter fur — in season, it is noble”. And then the chapter spends seven paragraphs showing that when climate is urgent, the ordinary rules step aside.
Winter Wood meeting Water. “Seal meeting Officer is called Officer and Seal complete — no one is not noble. But Wood in winter meeting Water, though the Officer star shows, cannot be counted noble: Metal is cold and Water only freezes more, and frozen Water cannot feed Wood.” A textbook Officer-Seal formation fails, because the season is wrong. But the same winter Wood with Fire showing is “especially elegant: winter Wood meeting Fire not only drains the body, it also regulates the climate.” The chapter's example is a minister's chart (Geng Yin, Wu Zi, Jia Yin, Bing Yin), where Wealth and Officer are both idle gods and only the Bing Fire in the hour does the work — draining the body and warming the season at once. Peng Yulin's chart (Bing Zi, Xin Chou, Wu Zi, Gui Chou) makes the same point for winter Earth: without Bing Fire to warm it, the Useful God never shows.
Metal-Water Wounding Officer in winter. “The Wounding Officer meeting the Officer brings calamity in a hundred forms — but Metal and Water meeting it is the opposite, elegant. It is not that the Officer does not fear the Wounding; it is that regulating the climate is urgent, and the chart uses it by weighing.” The chapter's example (Jia Shen, Bing Zi, Geng Chen, Jia Shen) is a winter Metal chart where the Wounding Officer is the only outlet for a strong body — and the commentator's note is exact: “Bing Fire for climate is what the combination cannot lack.” The same logic, reversed, governs summer: “The Wounding Officer paired with the Seal can be used at any time — but used in summer Wood, its elegance is a hundredfold: Fire relieves Water, Water relieves Fire.” The example (Geng Chen, Ren Wu, Jia Chen, Ding Mao) is praised for its balance: Ren Water moistens, Geng Metal feeds the Seal, two Chen branches drain the Fire's dryness.
Wealth, and the two famous pairs. “The Wounding Officer using Wealth is by nature a noble Pattern — but used in winter Water, even a small fortune is mostly not noble, for frozen Water cannot feed Wood.” And the same Pattern in summer Wood is “elegant, but not supremely elegant, for dry Earth is not very inspired.” Then the chapter's best-known sentence: “Spring Wood meeting Fire is Wood and Fire shining through — but summer Wood is not judged so. Autumn Metal meeting Water is Metal and Water containing each other — but winter Metal is not judged so. The breath has its flourishing and its decline; the choosing differs.” Spring Wood with Fire is the Wood-Fire illumination, and the Officer is not feared there; autumn Metal with Water is the Metal-Water containment, and the Officer is no obstacle there. The same pair of elements, a different season, the opposite verdict — which is why the chapter ends where it began: “There are many more such cases, and they cannot all be told. The student must extend by analogy, and understand by the spirit.”
The 120-cell table
The Qiong Tong Bao Jian turns that spirit into a table: for each Day Master, in each month, the elements the chart needs, in order — the first named is the chief requirement, the rest are its assistants. The table below is the book's “summary of the Useful God” (喜用提要), checked against three printed copies. Read a row by your Day Master, a column by your birth month branch. (Month branches run Yin through Chou — the first month to the twelfth — not January to December, because the chart follows solar terms, as Lesson 3 explains.)
| Day Master | Yin 寅 | Mao 卯 | Chen 辰 | Si 巳 | Wu 午 | Wei 未 | Shen 申 | You 酉 | Xu 戌 | Hai 亥 | Zi 子 | Chou 丑 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Jia 甲 Wood | 丙癸 | 庚丙丁戊己 | 庚丁壬 | 癸庚丁 | 癸庚丁 | 癸庚丁 | 庚丁壬 | 庚丁丙 | 庚甲丁壬癸 | 庚丁丙戊 | 丁庚丙 | 丁庚丙 |
| Yi 乙 Wood | 丙癸 | 丙癸 | 癸丙戊 | 癸 | 癸丙 | 癸丙 | 丙癸己 | 癸丙丁 | 癸辛 | 丙戊 | 丙 | 丙 |
| Bing 丙 Fire | 壬庚 | 壬己 | 壬甲 | 壬癸庚 | 壬庚 | 壬庚 | 壬戊 | 壬癸 | 甲壬 | 甲戊庚壬 | 壬戊己 | 壬甲 |
| Ding 丁 Fire | 甲庚 | 庚甲 | 甲庚 | 甲庚 | 壬庚癸 | 甲壬庚 | 甲庚丙戊 | 甲庚丙戊 | 甲庚戊 | 甲庚 | 甲庚 | 甲庚 |
| Wu 戊 Earth | 丙甲癸 | 丙甲癸 | 甲丙癸 | 甲丙癸 | 壬甲丙 | 癸丙甲 | 丙癸甲 | 丙癸 | 甲丙癸 | 甲丙 | 丙甲 | 丙甲 |
| Ji 己 Earth | 丙庚甲 | 甲癸丙 | 丙癸甲 | 癸丙 | 癸丙 | 癸丙 | 丙癸 | 丙癸 | 甲丙癸 | 丙甲戊 | 丙甲戊 | 丙甲戊 |
| Geng 庚 Metal | 戊甲壬丙丁 | 丁甲庚丙 | 甲丁壬癸 | 壬戊丙丁 | 壬癸 | 丁甲 | 丁甲 | 丁甲丙 | 甲壬 | 丁丙 | 丁甲丙 | 丙丁甲 |
| Xin 辛 Metal | 己壬庚 | 壬甲 | 壬甲 | 壬甲癸 | 壬己癸 | 壬庚甲 | 壬甲戊 | 壬甲 | 壬甲 | 壬丙 | 丙戊壬 | 丙壬戊己 |
| Ren 壬 Water | 庚丙戊 | 戊辛庚 | 甲庚 | 壬辛庚癸 | 癸庚辛 | 辛甲 | 戊丁 | 甲庚 | 甲丙 | 戊丙庚 | 戊丙 | 丙丁甲 |
| Gui 癸 Water | 辛丙 | 庚辛 | 丙辛甲 | 辛 | 庚辛壬癸 | 庚辛壬癸 | 丁 | 辛丙 | 辛甲壬癸 | 庚辛戊丁 | 丙辛 | 丙丁 |
Three patterns run through the whole table, and they are worth learning before any single cell. Wood Day Masters spend the year looking for Fire to warm them and Metal to shape them — Geng cuts Jia, Ding tempers Geng is the chain the book returns to again and again. Fire Day Masters spend the year looking for Water to cool them and Wood to feed them — Bing Fire is the sun, and the sun needs Ren Water the way a lamp needs shade. Metal Day Masters spend the year looking for Fire to forge them and Water to wash them — Geng loves Ding's hammering, Xin loves Ren's washing, and Xin most fears Ding's fire, which ruins a finished jewel. Water and Earth follow the same logic in reverse: what the season gives too much of, the table takes away; what it withholds, the table supplies.
The checker: does the chart have what its month asks for?
The table says what the month needs; the checker asks whether the chart actually has it. The chief requirement — the first character in the cell — decides the verdict: revealed in a heavenly stem, the climate is met; hidden only inside a branch, it is half met; absent entirely, we look for a substitute of the same element (Ren standing in for Gui, Bing for Ding) — if one shows, the climate is half met by substitution; if nothing shows, the climate is missed, and waits for the luck pillars to supply it. The assistants are reported the same way, stem by stem. The verdict is only about warmth and moisture — it never, by itself, says a chart is good or bad. A chart can form cleanly and still miss its climate, and a chart can meet its climate and still fail its Pattern. The three layers — forming (Lesson 9), rank (Lesson 10), climate (this lesson) — are read together, never one in place of the others.
Four charts, worked through
Mao Zedong, 26 December 1893, Chen hour — Gui Si, Jia Zi, Ding You, Jia Chen. Ding Fire born in Zi: the table asks for Jia Wood, then Geng Metal. Jia is revealed twice, in the month and hour stems — the climate is met. The Wood that transforms the Killings (Lesson 9) is also the Wood that warms the winter chart; one god does two jobs, which is why the classic calls winter Wood meeting Fire “especially elegant”.
1 October 1949, 3 p.m. — Ji Chou, Gui You, Jia Zi, Ren Shen. Jia Wood born in You: the table asks for Geng, Ding, Bing. Geng is hidden in the hour branch Shen — half met — and Ding and Bing are nowhere in the chart at all. The Pattern forms (Lesson 9) and stands low (Lesson 10), and the climate layer adds the third fact: autumn Wood with no Metal to shape it and no Fire to warm it. The chart's strength comes from its Wealth, Officer and Seal arrangement, not from its season — which is itself a useful thing to know, because it tells you where the luck pillars must help.
The classic's own winter Metal chart — Jia Shen, Bing Zi, Geng Chen, Jia Shen. Geng Metal born in Zi: the table asks for Ding, Jia, Bing. Ding is nowhere — not in a stem, not hidden in any branch. But Bing Fire is revealed in the month stem, the same element as Ding, and Jia Wood is revealed twice. The climate is half met by substitution — and the commentator's sentence lands exactly here: “Bing Fire for climate is what the combination cannot lack.” The substitution is not our invention; it is what the classic itself points at.
The classic's own summer Wood chart — Geng Chen, Ren Wu, Jia Chen, Ding Mao. Jia Wood born in Wu: the table asks for Gui, Geng, Ding. Gui is hidden in both Chen branches — half met — and Geng and Ding are both revealed. Ren Water shows in the month stem, and the commentator praises it: “delighting in Ren Water to moisten”. The chart is balanced, the commentator says, because the moisture is there in two forms at once — Gui hidden, Ren revealed — and the two Chen branches drain the Fire's dryness.
Three honest caveats. First, the table is the book's summary, not the book itself: the Qiong Tong Bao Jian divides some months in half (“after Rain Water, use Geng and Ding”, “first half of the month, then the second”), and the summary table does not. Our checker follows the whole month and flags the half-month question for a human eye. Second, the printed copies disagree in two places, and we print the disagreement rather than hiding it: for Jia Wood in You month, one copy makes Bing and Ding the chief requirement and the summary table makes Geng chief with Bing as assistant; and for Xin Metal in Zi month, three copies write “Bing, Wu, Ren, Shen” — Shen is a branch, not a stem, and looks like a copyist's extra character, so our table lists Bing, Wu and Ren and marks the cell as doubtful. Third, the table tells you what the season needs, not what the chart is worth. Climate is the third layer of a reading, after forming and rank — never a verdict on its own.
What this means in a reading
The Useful God is the medicine, the Pattern is the skeleton, and climate is the weather the medicine must work in. A chart born in deep winter with no Fire is not a bad chart — it is a chart whose luck pillars must bring Fire, and whose best years will be the warm ones. A chart born in high summer with Water revealed is not a lucky chart — it is a chart that can breathe, and the reading can move on to the harder questions of Pattern and rank. That is the whole point of the climate layer: it is checked first, because everything else is judged in the season it stands in. The next classic on the desk is the chapter On the Purity of the Useful God — and then the Patterns themselves, one by one.
