Day Pillar #16 · 己卯

"Jimao (己卯) — Same Nayin as Its Neighbour, Opposite Prescription: One Adds, One Removes"

Position in the cycle	#16 of 60
Heavenly stem 天干	己 — 土 Earth
Earthly branch 地支	卯 — 木 Wood
Nayin 纳音	城头土 — City-Wall Earth (Earth)
Hidden stems 藏干	乙 — 乙 (Wood)
Twelve-stage placement 十二长生	病 — Illness (of the stem in its own branch)

When a chart looks weak, almost every system says the same thing: add. Feed it, prop it up, strengthen the day master. Jimao (己卯) is the pillar where the classical text goes the other way, and it is only visible if you read it next to the pillar before it.

Two pillars, one nayin

己卯 and 戊寅 Wuyin share the nayin 城头土, city-wall earth. Same category, adjacent seats. You would expect roughly the same prescription. Here are the two lines, from the same register, a few characters apart:

戊寅土，堤阜城郭，喜木及火。

Wuyin earth: embankments and city walls. It likes wood, and fire.

己卯土，破堤败城，喜申酉及火。

Jimao earth: breached embankment, ruined wall. It likes Shen and You, and fire.

What Shen and You are doing there

申 Shen and 酉 You are the two metal branches. Metal cuts wood. And 酉 clashes 卯 directly — they sit opposite each other on the branch cycle.

Now look at what this pillar is made of. 己 is yin earth. It sits on 卯, and 卯 is wood — the sole hidden stem is 乙, wood again, with nothing else in the branch. The wood is not somewhere else in the chart. It is the seat.

So the remedy named here is not more earth and not more support. It is metal, to cut the wood, and 酉 specifically, to clash the branch the earth is standing on. The prescription is subtractive. One pillar gets built up; the other gets something taken away.

The verdicts follow the same split, and it turns on one character

己卯，自死之土。抑又甚焉。

Jimao: self-dying earth. And this is worse still.

Set that against 戊寅's 受伤之土 — wounded earth. Wounded means something did it to you. Self-dying means nobody had to. The 自 is carrying the whole difference.

And once you read it that way the prescription stops being surprising. If nothing external is doing the damage, then adding support is aimed at the wrong place — there is no wound to close. What you look at instead is what the thing is standing on. The register did not argue this out; it simply looked at the seat, and prescribed from the seat.

The book is not gentle about the image, either: 破堤败城, breached embankment and ruined wall, against 戊寅's intact 堤阜城郭. Same construction, one seat later, already given way.

The stage table agrees

己 at 卯 falls at 病, illness, in the twelve-stage cycle — while 戊 at 寅 falls at 长生, growth. Two adjacent pillars of the same nayin, and the deterministic table puts them at opposite ends of the cycle. The prescription split is not an inconsistency in the register. It is tracking something the tables also see.

What we are still holding back

The same entry has a second half that turns the whole judgement around — the 《五行要论》 passage on 散为和气. We have not written that up yet, because doing it properly means setting out how the two halves relate, and that is a longer piece than this page.

One thing we would like checked

The nayin section in our copy heads this pair 戊寅已卯城头土 — 已, not 己. 已 is neither a heavenly stem nor an earthly branch, so that pillar does not exist; the sexagenary cycle has no such combination. The same book prints 己卯 correctly in three other places, which makes this a single slip rather than a variant reading.

If you have a different edition of San Ming Tong Hui: what does yours print in that heading? We are collecting these.
