The biggest kept secret in Feng Shui industry is the combination of 5, the combination of 10, the combination of 15 and the combination of the Hetu, particularly in San Yuen Feng Shui system.
These combinations are not derived from the Flying star Feng Shui system. The flying star feng shui system does not have such combinations. The most unfavorable combination in Flying star system, perhaps, it is the 2-5 combination. However, it is not going to be discussed here.
I am going to discuss the combinations of 5, 10, 15 and Hetu here in the eight mansion system or 8 house system here. Most Feng Shui masters know the eight mansion system, however, may be they do not the theories behind or they are unwilling to tell you.
In fact the 4 auspicious sectors in the Eight House feng shui system comes from the combinations of 5, 10, 15 and Hetu. I will show you how these come about. These four auspicious sectors are:
The Sheng Qi (生氣) is the combination of Hetu (16 water, 27 Fire, 38 Wood, 49 Metal)
The Yan Nian (延年) is the combination of 10
The Tian Yi (天醫) is the combination of the 5 and 15.
Fu Wei. (伏位) is the self-position or the same family.
You may be discovered the Earth element combination in Hetu is located at the center. And the center is the Wu 戊 and Ji 己. There is a saying in Chinese “有土斯有財”. This means “have got earth have got wealth”. So the combination in to 5, 10, and 15 are to create 5, which is the earth element. As the result the Feng Shui wealth follows. Now let give you the explanation the combination in eight house feng shui system. The 8 mansion feng shui system comes from the Early Heaven Bagua order and the Loshu chart sequence. Here is the diagram of the Early Heaven Bagua and Loshu chart showing how the Sheng Qi were derived If you understand this diagram, you can work out other combinations.
