Hi Bill, I take it that when you say (+) direction and (-) , you mean yang (forward) and yin (reverse) paths taken by mountain and water stars. To be honest, it is quite hard to explain this task in an e-mail as there is a chart that you look at to determine the forward(yang) and reverse(yin) sequence of mountain and facing/water stars. A circle is divided into 24 mountains/sitting. And, each mountain is assigned a yin or a yang. If your house facing or sitting happens to fall into a yang category, then it follows a forward path. If it falls under a yin category, then it follows a reverse path. Perhaps if it's not an urgent matter for you to learn it, maybe you can wait for Cecil's flying star course.
