For your life to work well, it is vital to have a good flow of clear, vibrant energy in your home and workplace. Feng shui is a beautifully organized system of knowledge that allows us to design buildings to maximize the beneficial flows of energy around us by improving building design, furniture placement, colour schemes, and so on. It is based on having an understanding of the essential qualities of chi, and how to keep it fresh and vital through balancing the elements of Nature in our environment.
The Chinese name "feng shui" describes the system that is best known in the West and most easily transposes to the western way of life, but most traditional cultures have their own form of feng shui that they have used for thousands of years. Traditional systems do not take account of the harmful effects of electromagnetic fields that are so prevalent in our homes today, or do not include checking for geopathic stress before positioning key items of furniture such as beds, desks, sofas and chairs. Some modern systems of feng shui may also have become entangled with local superstitions or New Age add-ons. But the core principles have stood the test of time, and are the same today as those formulated and practiced in ancient times.
Very few western buildings are so well designed that there are no areas where energy gets stuck. Most are conceived without any thought being given to the way energy can flow around them, and awkwardly positioned furniture can then add to the problems. How much stuck energy builds up depends on the overall feng shui of a place and the activities of the people who occupy it. Feng shui always works better and faster when done in conjunction with space clearing, and space clearers are often called in to help where a feng shui professional has done all they can do but the situation still hasn't improved or hasn't improved enough.
