The identification of the favorable and supportive deities (喜用神) based on the day stem (日干) is a key technique in studying the Qimen Dunjia. By using online divination and self-testing methods, one can better understand and apply the concept of favorable and supportive deities.

Online Divination for Favorable and Supportive Deities

During online divination, the fortune teller helps interpret the chart based on the client's birth chart (八字). In this case, the day stem represents the client themselves. Another scenario occurs when the client consults the fortune teller; after the fortune teller casts the hexagram, the day stem represents the fortune teller, while the client should focus on the month stem.

Self-Testing Techniques for Favorable and Supportive Deities

When a fortune teller conducts self-testing, the day stem serves as the favorable deity. If testing for a specific relative or someone else's matter, the month stem becomes the favorable deity. In Qimen, the favorable deity has greater influence when it is on the "four pillars" (四纲), and if it is not on the four pillars, the success rate will be lower. Therefore, the impact of the four pillars must be taken seriously.

Selecting the Favorable Deity Based on the Yearly Destiny (年命)

Selecting the favorable deity based on the yearly destiny (年命) is a common method. It involves identifying the characteristics of the client's birth year and can also consider techniques such as the horse star (马星) or the position of time stems (时间落宫) to determine the favorable deity, applying different methods flexibly.

How to identify the favorable and supportive deity based on the day stem is crucial in learning Qimen Dunjia. By using online divination, self-testing techniques, and the method of selecting the favorable deity based on the yearly destiny, one can better understand and apply the concept of favorable and supportive deities, thereby improving the accuracy and depth of predictions.
