Hi everyone.
There is one essential aspect of the WWG system that I do not understand. It is said that the casting date is one of the most important aspects. In Jack Chiu's book it says: "Since casting is to seize the revelation of the divine power in a particular day, so the day branch of the day of casting will have determining effect onto the Vulnerable as well as all of the lines in the hexagram." And in "The Gold Yarrows" book is said: "The day branch is the master of the 6 lines". (Note: The Vulnerables is Yong Shen).
I ask myself, what is the use of valuing all the forces of the Day/Month/Year effect of the casting (Sheng, Ke, Chong, He), besides aspects like a San He formed (with Day or Month), or Kong Wan, on the lines of the hexagram to value the auspicious or inauspicious, if in the future the hexagram obtained will be affected by a Day/Month/Year different from the Day of the casting???. On the day that the event occurs for which we ask, with a known date determined, the influence of Day/Month/Year will be different (different earthly branches), changing the interpretation quite a bit or completely.
For example, in a litigation, an exam, a wedding, a trip, a work interview, a date of a sports event...(any event where we have a specific calendar date established); they are events that we know will happen on a particular date, or a particular month, or a particular week of the calendar. The day of the casting we have a wonderful setting or configuration (ex: Yong Shen is vitalized and in conjunction (He) with to Day and Month, besides we have a San He that generates the subject line, and it is not in Void) but it turns out that the day of the event happens the opposite (the Yong Shen is influenced by Ke, Chong, Month breaker, San He broken or not formed, Kong wan, etc...), that is to say, any negative aspect that changes the initial interpretation. The opposite could also happen, the case of a hexagram that is very negatively affected by the Day/Month/Year of the casting and, however, on the date of the event the influence of the Day/Month/Year will be very good.
Then, what is more important? The day of the casting or the period of time (or specific date) when the event will take place? How to deal with the contradictions of the effects of the casting day and the effects of the event day?
I hope I've made myself clear; the subject is a bit of a mess.
Greetings to all.
