Bazhai or Eight Houses Setout
August 31, 2008
There are different theories as to why the East Four Houses are located at Zhen (east), Li (south), Xun (SE) and Kan (north), while the West Four Houses are located at Qian (NW), Dui (west), Kun (SW) and Gen (NE). Here is one theory based on using the Early Heaven Bagua with the Later Heaven Luoshu Numbers by applying the Yijing principle, “Early Heaven is the Ti (Principle) and Later Heaven is the Yong (Function)”.
If we look at th diagram below, we can see the Hetu pairing of 4,9 Metal generates 1,6 Water and 3,8 Wood generates 2,7 Fire, thus giving the two groups of Zhen, Li, Xun and Kan, with Qian, Dui, Kun and Gen, making them the East Four and West Four grouping respectively, and forming the two arms of a cross.
The justification for this explanation is the Yang facings need Yin water and the Yin facings need Yang water to make the intercourse of Yin and Yang complete. The Yang in this case refers to the odd numbers with their related Gua, namely 9 (Qian), 1 (Kun), 7 (Kan) and 3 (Li), while the Yin refers to the even numbers with their related Gua, namely 6 (Gen), 4 (Dui), 8 (Zhen) and 2 (Xun). As shown in the diagram, each Yang number faces a Yin number and vice versa, so for this reason, it is not desirable to mix neither the “East” with the “West” nor the “West” with the “East”.
