In my own training and the training that I give my students, the principle “tool” is a mental map called a bagua. This bagua is superimposed over a space based on the position of the front door and from which can be determined the nine life areas (Career, Knowledge, Family, Wealth, Fame, Partnerships, Children & Creativity, Helpful People, and Health). By determining where an issue is specifically represented on the main floor of the space, a person can gain insight about what kind of changes can or should be made for an optimal outcome. This past week someone asked how the bagua should be placed on an upper floor. This question implies some other questions: Is there a front door upstairs and where is it? Or is the bagua the same from one floor to the next?
