You understand who you are, you know what your purpose in life is, and you realize how to deal with problems. In the philosophy of feng shui, before you were born, you existed as part of the five elements in nature. It also tells you the direction your energy flows in and which of the EarthLikewise, the year a building came into being, its location, orientation, the colors and material, exterior landscaping - thirty factors in all, will have an impact on you, the person living inside. If we look at only one of these aspects, the hallway per se, it alone has little affect on you. It is the combination of everything about your house along with you and the planets that must be evaluated in order for a sound feng shui analysis to be made.
People are a product of their specific environment.
Once we know what we are made of, we can begin to understand how everything else, also made of the five elements, affects us. For example, if you are born in 1952, your birth element is called zhen, it is a wood element energy associated with the eastern direction. Having your bedroom in the eastern part of your house makes you feel comfortable and able to sleep well. You would want to avoid metal energies such as white and the western direction that defeat wood. For instance, a white colored office that is located on the west side of the building can make you may feel tired easily and unproductive.
