Most people with some knowledge of Feng Shui will have heard of Personal 8 Mansions or Ming Gua. It is the most talked about of the two 8 Mansions Methods and categorises each person as either East Group or West Group.
This is further fine-tuned by a Gua number (a number between 1 and 9) based on birth date and whether they are male or female. East Group Gua are 1, 3, 4 and 9. West Group Gua are 2, 5*, 6, 7 and 8.
5* is treated differently. In the original Luo Shu Grid the number 5 Earth Star was placed in the central palace. As this has no place directly in the 8 Mansions system any person who has this number based on their birth date takes the following alternative Earth Stars.
*Male with Gua 5 receives Gua 2 energy
*Female with Gua 5 receives Gua 8 energy
Four good and four bad personal directions are attributable to each Gua.
The Gua numbers have a set place around the compass based on the original Luo Shu Grid as well as an associated element:
|The Special Gua '5'|
|5 Male||Use South West||Earth|
|5 Female||Use North East||Earth|
|Gua||Life Generating||Heavenly Doctor||Longevity||Stability|
|Sheng Qi||Tian Yi||Yan Nian||Fu Wei|
|2||North East||West||North West||South West|
|5 Male use 2||North East||West||North West||South West|
|5 Female use 8||South West||North West||West||North East|
|6||West||North East||South West||North West|
|7||North West||South West||North East||West|
|8||South West||North West||West||North East|
|Gua||Bad Luck||Five Ghosts||Six Killings||Total Loss|
|Huo Hai||Wu Gui||Liu Sha||Jue Ming|
|1||West||North East||North West||South West|
|3||South West||North West||North East||West|
|4||North West||South West||West||North East|
|5 Male use 2||East||South East||South||North|
|5 Female use 8||South||North||East||South East|
|9||North East||West||South West||North West|
The simplistic view of Personal 8 Mansions is that if you face one of your good directions and avoid one of your bad directions things will work out and by knowing your Gua number and the location it occupies around the compass you can use that location when you work and play.
In reality it is a little more complicated. Those with Gua number 1 for example. The location for 1 is the North yet in the above list North is only the fourth best direction for Gua 1. It would be helpful to them but not in every circumstance.
What would Gua 1 do if their main door was located in Jue Ming location? Move house or change office? This is where 8 Mansions Home comes in.
