A San Yuan Luo Pan containing the 64 Hexagrams of Xuan Kong Da Gua is required in order to practice San Yuan Qi Men Dun Jia. The Xuan Kong Da Gua method of selecting an auspicious time to commence an action only allows us to identify the appropriate ‘Chinese Hour’. One Chinese Hour is equivalent to two Western Hours. It allows us to identify within this Chinese Hour the exact ‘moment’ when the action must commence in order to obtain a guaranteed result. This ‘moment’ is when a predefined phenomenon is observed to occur.
The effectiveness of applying Qi Men Dun Jia in actual practice lies in our ability to observe the occurrence of the predefined phenomena. Sometimes the phenomena take a slightly different form compared to what have been described in the old text and it takes an experienced practitioner to spot it.
