真假論
This chapter supplies the test that every other chapter assumes. An element is 真 not because it is present but because the season is behind it; the same element in the wrong month is 假, and using it produces an ordinary life however impressive the chart looks. It matters because the chapter then admits a third outcome — a chart where true and false cannot be separated at all — and names that as the most quietly damaging case of the three.
| Classical term | Rendered here | What it actually does |
|---|---|---|
| 真 (zhēn) | true / genuine | In this chapter, an element that holds the season and can therefore be put to use. A functional status, not a moral one and not a statement about whether the element exists. |
| 假 (jiǎ) | false / spurious | An element that is present yet has not obtained the season, so that using it yields nothing. 假神 is not a missing element and not a weak one; it is an unusable one. |
| 提綱 (tí gāng) | guiding cord (the month branch) | The month pillar, treated as the handle by which the whole chart is carried. 提綱不照: the month command gives the Day Master no light to work by. |
| 黨 (dǎng) | party / faction | The supporting camp an element can muster — its frame, its allies, its reinforcements counted together. 黨多 is the second axis of strength after 得令, and the chapter keeps the two deliberately separate. |
| 屯否 (zhūn pǐ) | blockage and stagnation | From hexagrams 3 (屯, difficulty at the outset) and 12 (否, standstill). Used here for a life that neither collapses nor opens: no great calamity, no ease either. |
| 用神 (yòng shén) | Useful God | The element the chart is organised around and puts to work. The chapter's point is that a Useful God can be chosen wrongly — 用金水 in a Wood-Fire month is a choice the chart cannot honour. |
| 忌神 (jì shén) | Unfavourable God | The element that damages the Useful God when it intrudes. 不為忌神所害 is the condition for the true god to do its work. |
| 暗邀 / 暗化 (àn yāo / àn huà) | secret summon / hidden transformation | Branch and stem relations that operate without appearing on the surface of the chart: Si and Chou drawing in You, Yi and Geng transforming unannounced. The chapter treats these as capable of making a chart 真 after a first reading has ruled it out. |
| 日主 (rì zhǔ) | Day Master | The stem of the day pillar: the point whose fortunes the whole chart describes, and the thing the month command either illuminates or leaves in the dark. |
The chapter's first move is to separate two things that casual reading fuses. An element can hold the season (得令) or it can hold a frame — a combination, a party, a set of allies (得局而黨多) — and it can do one without the other. The whole middle passage is generated by permuting these: true with the season and false with the party; false with the season and true with the party; both with the season and both reinforced.
That separation is what makes 真假 a usable test rather than a compliment. If truth were simply strength, the strongest element would always be 真 and the chapter would have nothing to say. Because truth is <em>command of the month</em>, a chart can contain a large and well-connected element that is nonetheless false, and the reading turns on which of the two axes the chart actually has. Note also which axis the text rates higher: in every permutation it names, the season is stated first and the party second, and the case where the two axes are split is precisely the case it calls untraceable.
Most treatments of true and false stop at two results — the good chart and the bad one. This chapter adds a third and gives it the most space: 真假皆得令得助,不能辨其勝負. Both sides hold the season, both are reinforced, and no verdict can be reached. The stated consequence is exact and worth sitting with: 雖無大禍,一生屯否而少安樂 — no great calamity, and a whole life of standing still.
My reading is that this is the chapter's real target, and the reason it was written. A clearly bad chart at least has a direction: something is to be drained, something supported, and the work is defined. An unresolvable chart has no handle, so nothing can be corrected and nothing can be decided, year after year. In practice this is the chart that generates the most contradictory consultations — one reader calls it strong, another weak, both are defensible, and the person lives in the gap. The chapter's honesty is to refuse a verdict here rather than manufacture one, and to say plainly what refusing costs.
The Yin-month chart that shows Metal and Water on the stems instead of Wood and Fire has just been declared 提綱不照 — the month gives it no light. Then the text immediately reverses itself: Si and Chou summon You in secret, Wu and Si generate Metal in turn, You clashes Mao, Yi and Geng transform unseen, the qi turns west — 亦為有真, 亦或發福, this too has something true in it, and may prosper.
The two halves are not in contradiction, and the reconciliation is the practical lesson. The first reading of a chart is made on what is exposed — stems, month, visible structure — and that reading can be wrong, because the operators listed here act through branches, clashes, and stem pairings that never announce themselves. The word 暗 is doing the work twice over: these relations are unexposed, and they are the ones that decide. A reading that stops at the surface will dismiss a chart like this as mediocre when the machinery to carry it was in the branches all along.
The closing list confirms the scope. 會局, 合神, 從化, 用神, 精神, 形象, 才德邪正, 緩急, 生死, 進退 — every topic the treatise treats elsewhere is gathered here and told that it too has a true and a false version. 真假論 is therefore not one chapter among many but the discipline applied to all of them: whatever a chapter concludes about a chart, this one asks whether the thing it concluded on is commanding the season or merely present. That is also why 最宜詳辨 falls on the last line rather than the first — the discrimination is not a preliminary, it is the work.
