The most important thing to understand is that feng shui is really about the energy that's surrounding you in your personal space.

The structures around you also emanate energy, ... and if these structures are placed in a harmonious fashion based on feng shui guidelines, you attract good energy, and therefore you attract good fortune and good luck.

I always tell people that it's not very good to put water features in a bedroom -- not even paintings of lakes and rivers -- because that could lead to losses, particularly financial losses. Sometimes it also leads to a loss in relationship.
