what is feng shui i can use for prosperity?

for prosperity, easy.

using flying star method, put a moving water feature at the current water star location. the location differs in every location, so you need a fengshui pro to do the calculation.

using water dragon, put an incoming water in the good direction and outgoing water at the bad direction. in every house, there is about 4 directions that are good to you and 4 that is bad for you. making water flow towards the good, brings good energy to you; while, making water to flow against the bad direction, cancels the bad. this method makes 2x good while cancelling the bad. again you need a fengshui pro to do it for you as it differs in every house.

determine the busiest location outside the house - in terms of degrees and using xuan kong da gua, calculate what degree your main door should face or be tilted to attract the busy business outside inward.

using 5 ghost carry money to make your employees work harder, without them knowing it.

using 8 mansions, locate and face the stove in the right direction to attract wealth into your life.

these are just some of the methods, there are many fengshui methods out there to make you richer. each method involve a certain understanding of the concept, how to calculate for the needed info and applying these into your home. fengshui is not as easy as most people think. it involves precise calculation and application of the concepts. one slight deviation for example, you need 59 degrees, but because the door is old and it faces 60.5 degrees instead - then the effect will be totally different from the one intended.

fengshui is not putting a green frog at the farthest point of your house and uyou will get rich. this is what people who want you to buy their frog statues want you to believe - that a quick fix is a dollar away. but in reality, fengshui is more complicated than that.

It really depends on what type of Feng Shui you want to know more of: the new age type (where everything is generalized, no calculations, etc) or the classical type (recognized individuality and solutions provided from calculations).

Directly translated Feng Shui in chinese means "wind and water". But the full meaning of it is "the flow of wind and water in life". In a nutshell, Feng Shui is a chinese practice/science of achieving harmony through your surroundings and pursuing your aspirations.

In my opinion, all of this is ridiculous --- really ridiculous.
