The Ore and the Blade

The character

Counting through the ten heavenly stems, 庚 (gēng) comes seventh. Its element is Metal, and its polarity is Yang. Its partner, the Yin Metal, is 辛 (xīn). If 辛 is the jewel and the fine needle, then 庚 is everything heavy and unfinished that metal can be: the axe head, the iron bar, the anvil, the raw steel, the sword before anyone has polished it. A hand holding a 庚 object feels its weight before it sees its shape.

The old texts can put this stem in a single couplet. The Dī Tiān Suǐ (滴天髓), a Ziping classic that BaZi readers still quote, gives eight short lines to 庚, and this book follows the edition with the commentary of Rèn Tiěqiáo (滴天髓闡微). We will take the lines one at a time below. Most of the stem is in the first two: 庚金帶煞, 剛健為最. Geng Metal carries a killing edge, and in hardness and strength it stands first among the stems.

The word 煞 (shā) is the one to stop on. It is the same shā as in the Ten God Seven Killings, 七殺, which is often written 七煞, and the editions of the oldest note on the verse use both characters here. It names a force that cuts, checks and punishes. Rèn Tiěqiáo reads it as the severe, killing air of autumn (秋天肅殺之氣). Metal in the cycle of the five elements is the element of the blade, the border, the verdict and the clean line. A person whose Day Master is 庚 carries that quality in the middle of the chart. Others feel it before the person has said anything.

The verse, line by line

The other common edition, the Dī Tiān Suǐ Jí Yào (滴天髓輯要), reads 剛強為最, "hard and strong", in the second line and 能勝甲兄, "can defeat", in the seventh; the sense stays the same.

In plain words, the first two lines say what the metal is. Hard and strong, with an edge on it. People with this Day Master are often described as firm, direct and hard to bend, and the classics treat that as the nature of the stem, with no apology.

The third and fourth lines say what improves it. Water makes metal clear. Anyone who has washed a knife or watched a blade come out of a quench knows the picture: the dull skin goes, the bright steel stays. Fire makes metal keen. A bar left alone is a bar, and a bar that has been heated and hammered is a tool. Rèn Tiěqiáo is specific about both. The water he means is 壬, the Yang Water, which draws off the hard, killing temper and leaves the metal "tempered and crystal bright" (淬厲晶瑩). The fire is 丁, the soft Yin Fire, which does not fight the metal: in a good smith's hands it melts it down, "and it becomes swords and halberds" (遂成劍戟). The two lines give the book its second picture, which we meet in a moment.

The fifth and sixth lines are about the ground the metal lies in. Metal comes out of earth, and the verse says it is born there from damp, living soil. Dry, baked earth gives nothing, and metal caught in it turns brittle, like a bar left too long in the fire. The commentary names the branches: 丑 and 辰 are the moist earth, 未 and 戌 the dry, and the rule weighs most for a 庚 born in spring or summer, when its strength runs a little low (生於春夏，其氣稍弱). Soil is food for this stem, and dry soil is hunger.

The last two lines are a pair. Jia is the great Yang Wood, the tall tree, and Geng can fell it. Jia, first of the stems and Yang, is the "elder brother"; Yi, Yin Wood, the vine and the flower, is the "younger sister". The axe wins against the tree. Against Yi it loses, and the reason is the bond between them: 乙 and 庚 form one of the five stem combinations (乙庚合), and the soft partner holds the hard one by drawing it close. The commentators part ways here. The oldest note says that in this combination the metal grows weaker (合而反弱). Rèn Tiěqiáo answers that the pair turns affectionate (轉覺有情), that 庚 is not always weakened by it, and that each chart has to be judged on its own. Either way the lines match a familiar sight: the person who stands up to every large challenge and gives way before a small kindness.

The ore and the blade

The website calls 庚 the axe and the raw steel. Two pictures work better than one here, since a single image flatters.

The first is the ore. A seam of iron in the rock has weight and has a future, and for the moment it has no shape. It is dark, rough and heavy for its size. Everything that is later said about this Day Master starts here: the honesty, the stubbornness, the habit of saying a thing flatly because that is how it is. Ore does not apologise for being ore. It also does not know yet what it will be used for, and nobody has asked it. The old texts have a word for metal in this state, 頑金, "stubborn metal": the Shén Fēng Tōng Kǎo (神峰通考) uses it for autumn metal that no fire of 丙 or 丁 has worked, and quotes the common saying for such metal: "a lump of dead iron" (一塊死鐵).

The second is the blade. Take the same iron, put it through fire and hammer, plunge it in water, and grind an edge on it. A blade has a purpose, a balance and a limit. Think of the Chinese straight sword, the jian (劍): two edges, a point, a spine that runs true. It does not hack. It cuts when someone decides it should, and between cuts it rests in a scabbard. The words 得火而銳, 得水而清 describe the making of exactly this object.

Much of the life of 庚 is a slow passage from ore to blade. Ore is strong and has no use until it is worked. A blade is strong and has a use, but it has been through heat that the ore never knew. The price of the change is real: the fire hurts, the quench is a shock, the grinding takes away material. When this book speaks about strength and its price, about pressure, about sharpness and about rest, it is asking one question. What has this metal been put through, and who holds it now?

Neither picture is better. Ore that refuses all working stays in the hill. A blade that is never sheathed dulls, nicks and cuts the people closest to it. A reader with 庚 will usually want to keep both pictures in view.

A warning goes with both. In his commentary Rèn Tiěqiáo lists the comparisons that the fortune-tellers' rhymes had made familiar, one object for each stem, and for 庚 the object is stubborn iron (庚為頑鐵), close to the word quoted above. Using such comparisons to judge a life, he says, is a great error (大謬): 庚 and 辛 are one Metal, and what separates them is only Yang firmness and Yin softness. This book therefore keeps the ore and the blade as pictures for learning. They sketch a temperament, and they never stand in for the stem itself.

The neighbours of 庚 in the five elements

Five elements, two cycles: each one feeds a neighbour and holds another in check. Standing at 庚, the picture is:

One detail before we go on. Polarity does the fine sorting. Because 庚 is Yang, a Yang stem takes the same-polarity name of its element (Friend, Eating God, Indirect Wealth, Seven Killings or Indirect Resource), and a Yin stem takes the other one (Rob Wealth, Hurting Officer, Direct Wealth, Direct Officer or Direct Resource). Take wood: 甲 shares the Yang polarity of 庚 and so is Indirect Wealth, while 乙, being Yin, is Direct Wealth. The same logic makes 丙 (Yang Fire) the Seven Killings, and 丁 (Yin Fire) the Direct Officer. Chapter 3 takes its names from this table, and every chart in the book follows it.

Six readers

Six invented people keep us company, all with 庚 as Day Master. Four of them, born in four seasons, are in the table below. Each chart comes from the solar calendar.

The two others are Shirin (庚辰, born 23 August 1971) and Thabo (庚戌, born 13 September 1984). They turn up in the scenes from Chapter 2 on, and Chapter 9 reads their charts in full, so that each of the six Geng day pillars has a reader.

The rows go year, month, day, hour, the same order the calculator at bazi.cards uses for the four columns of a chart from left to right. Read the bold 庚 in each column as the Day Master. The character that follows it in the cell is the day branch, which stands under the Day Master in a chart: the seat of home and the nearest partner. Nothing needs decoding yet. Just look at the general feel of each chart. Gonzalo sits on Wood, with more Wood in his month and at the head of his hour, and two Metal branches at the two ends of his chart. Mei Ling's chart is crowded with Fire. Joost sits in the season of his own element, with Water and Fire on top. Oksana's is mostly Water, with a lamp of Fire at each end: 丁 in the year and 午 at the hour. Four blades, four different weathers. Later chapters let them meet the same rules from four different directions.

A scene: two evenings

Gonzalo is thirty-four and works as a structural inspector in Lima. At half past six in the evening he is the last person in the site office, going through a report that was due at five. A younger colleague has asked him twice whether a weld detail could be signed off. He said no twice, politely, with the reason in one sentence. She went away irritated and came back an hour later with the repaired drawing. Nobody thanked him, and he did not expect it. He ticked the box, and the pencil mark was straight.

If you asked him what he is like, he would say "fair" and perhaps "a bit blunt". His mother, on the phone, says he sounds like his grandfather who made hinges. He has no wish to be hard, and he finds it simply impossible to say that a bad joint is good.

Mei Ling's evening looks different. She is sixty, retired from running a printing firm in Singapore, and she is sharpening kitchen knives for her neighbours on a Thursday, as she has done for years. Three people come to the door each month. She has never charged. She says that a knife which cuts clean is a small mercy, and she looks pleased and slightly severe at the same moment, which her grandchildren have learned to read as love.

This is 庚 in its everyday forms: a standard held without ceremony, a service that arrives as a precise act. Chapter 2 asks what that costs.

What this book leaves out

It makes no forecasts. This book reads BaZi in the Ziping tradition as a description of climate: which forces stand in the chart, where they push and where they hold. Dates of events are outside what it attempts, and the careful wording of the pages ahead ("often", "usually", "the chart leans") is deliberate.

Nor does it advise on body, money or law. Those chapters work in images and questions, and any practical step belongs with a qualified person.

What the book offers is a clear glass. A first reading can come as a relief: a quality you were told to file down is described calmly, as a property of the stem. If that happens, notice it. The old verse ranks this stem first in hardness and strength, and it says so without blame.
