What is the remedy/cure for the
following situation:
When the natural order of Green and
White Tiger is reversed? i.e. The West
Tiger side is higher than the Green
Dragon side. For the owner of the middle
house for example, will become
"dominated." For example, if he has a
son, his son would dominate the house or
if he has a mistress, he will be
dominated by his mistress and she will
be more the fortunate than the owner.

Frankly, it is difficult to change the external factors, since majority or all the time, we do not have control over this. It is not like, one can get the dragon side to be higher than what it is or the tiger side -- lower. This is not just possible.

Thus, you have to consider maximizing the FengShui of your home by other means i.e. improve other areas of your home, instead.
