Fengshui means the Law of Heaven and Earth. Feng means wind and Shui means Water. It believes in the balance of yin and yang (the two opposites) and a balance between Heaven and Earth. Chinese saw wind and water as the intermediaries between heaven and earth.
The earliest records of Fengshui can be established during the Han Dynasty (200B.C – 200 A.D). There is evidence that the Chinese wrote on bones about the logical assumptions of natural cause and effect. The observation of Nature’s cycle and it’s relationship with the well being of humans. However, it is also believed that the Buddhist monks travelled to Tibet to teach and preach Lord Buddha’s teachings.Along with the Buddhist philosophies they also carried with them other systems which were practised and perfected in India. Vastu was one amongst them. The beliefs slowly altered to suit the local customs and culture.
Fengshui too takes into account the importance of the 5 elements and the 4 directions. But it also lays a lot of emphasis on flow of “chi” or the cosmic energy. It is the invisible life energy force which operates within a human body as well as the buildings we live in. A building without proper flow of chi is nothing but an ailing or dead concrete structure. The philosophy behind Fengshui is to create environments where the chi flows smoothly to achieve physical and mental health.
Not only South East Asia but the Western world too in-corporate Fengshui principles and considers it as an effective tool. In Taiwan whenever a new skyscraper goes up the owners hire a Fengshui consultant to plan and build their buildings. Fengshui is thousands of years old philosophy but its principles are as much relevant today.
Looked at another way, such a home on the south slope gets the maximum hours of sunlight, is shielded from the chilly, health-sapping north wind and has a good supply of water for drinking and cleaning. By then conveniently disappearing under the ground and gravel, the river carries away effluents and other "dirty" water.
Therefore with a little foresight and a good knowledge of Fengshui we can select the best place for ourselves.
