What the Ten Gods Are: How to Read Bi Jian, Zheng Cai and Qi Sha
A friend brought me a fortune book and asked: "Mine says Qi Sha here — does that mean my fate is bad?"
I did not answer directly. I asked her first: do you know which character on this chart is "you"?
She leafed through it for a long while and pointed to the third character.
Wrong. That was the heavenly stem of the month pillar — the heavenly stem of the day pillar is the fifth character along.
The Ten Gods are a set of relations derived from the Day Master
The Ten Gods are not gods; they are the names of a set of relations. Fate calculation takes the heavenly stem of the day pillar (the Day Master) as its centre and divides its five-phase relations with the other seven characters into ten categories: the ones we read as Bi Jian, Jie Cai, Shi Shen, Shang Guan, Pian Cai, Zheng Cai, Qi Sha, Zheng Guan, Pian Yin and Zheng Yin.
The way they are sorted is this: what is the same as me is bi-jie, what I generate is shi-shang, what I control is cai, what controls me is guan-sha, and what generates me is yin (resource/seal). So the same character, placed in different charts, may turn out to be Zheng Cai or Qi Sha — it depends on where it sits relative to the Day Master.
This terminology took shape within the Ziping line, and the fate-calculation texts of the Ming and Qing already contain the complete division (sources 1 and 2).
The names describe relations, not good or bad fortune
This is the point most easily confused.
The name "Qi Sha" sounds fierce, but what it describes is one layer of relation: the thing that controls me and shares my polarity. "Control" resembles a bad thing in everyday language; in fate calculation it is simply one of five relations.
"Zheng Guan" sounds respectable, and it also describes a relation: what controls me and has the opposite polarity to mine. Whether that relation lands on you as something good or something bad depends on the overall structure; the name itself carries no verdict.
I once did some plodding work: I copied the ten names onto paper and drew arrows by five-phase relation, starting from the Day Master and linking outward layer by layer. It took three rounds before I stopped having to go back and check "which two of these go together".
The right order for reading the Ten Gods
Step one, fix the Day Master. The heavenly stem of the day pillar, that is, "me". Without this step, everything that follows is idling.
Step two, look at numbers. Among the ten relations, which kind appears often and which kind not at all. A relation that clusters tends to be a theme that recurs in your life.
Step three, look at position. The same relation falling in the year pillar and falling in the hour pillar corresponds to different stages of life and different people.
Step four, and only then, look at favourable and unfavourable elements and at the pattern.
To skip the first three steps and jump straight to the fourth is the commonest way of explaining charts on the market — it sounds very professional, but swap in another person and the conclusion usually fits them just as well.
Two misunderstandings I am often asked about
The first: "does having many Ten Gods mean a good fate?" No. The Ten Gods are relations, not a score.
The second: "I have only one Zheng Yin — is something missing?" No either. There is no notion of missing or not missing among the Ten Gods, only frequency and position.
What is really worth asking is this: that relation which keeps recurring — in your own life, which people and which matters does it correspond to? The fortune book cannot give you the answer to that question; only you can fill it in.
