Selecting the Useful Spirit (Yong Shen)
The Useful Spirit is the "anchor" of Qi Men Dun Jia readings — whatever question is asked, the corresponding star, gate, and stem become the object of analysis. Choose the wrong Useful Spirit, and the entire chart goes wrong.
General Rules
- Day Stem = the querent themselves; Hour Stem = the matter in question (also represents juniors/subordinates)
- The Year Life (the heavenly stem of the querent's birth year) falling in a palace represents the innate foundation, which can be consulted as a supplement
- For the Useful Spirit, first examine the strength or weakness of its palace (the palace's Five-Element vs. the generating/overcoming relationships with the spirit's/gate's/star's Five-Element), then examine the pattern's responses

Judging Auspiciousness and Inauspiciousness through Generating and Overcoming
- The Useful Spirit's palace generates me (the Day Stem's palace) → the matter comes to me; smooth
- I generate the Useful Spirit's palace → I need to put in effort; achievable with exertion
- The Useful Spirit overcomes me → the matter pressures me, beware of obstacles; I overcome the Useful Spirit → I can take control
- The Useful Spirit's palace is Void (空亡) → the matter is illusory / delayed / comes to nothing; timing is indicated when it emerges from Void (the Void's Earthly Branch meets its ruling period)
- The Useful Spirit enters tomb / Punishment (击刑) / Gate Pressure (门迫) → trapped and constrained
