Feng Shui is the art of creating balance and harmony in our surroundings. Over 3,000 years ago, it was developed in China and attributable to its origin, it is also called Chinese Feng Shui. Feng Shui is actually an ancient art and science, besides being a compound body of knowledge. It proclaims different ways that facilitate balance of energies in the environment, so that people inhabiting the place enjoy sound health, wealth and are blessed by good fortune. The term 'Feng' suggests 'wind', whereas 'Shui' suggests 'water'.The Chinese culture has always given importance to wind and water, which are associated with good harvest and good health. As a result, 'Good Feng Shui' became the theory of livelihood and fortune and 'Bad Feng Shui' suggested destitution and hardship. Anchored in the Taoist vision, Feng Shui is about an understanding of nature and specifically the land that is considered to be alive and full of energy. Earlier the Chinese used to believe that land's energy could create as well as shatter any kingdom.Main door of the house is known as the 'Mouth of Chi'. The house absorbs energy or Chi through the main door. Therefore, it is very important to have a good main entrance, which attracts high levels of energy to improve the life of the occupants. To ensure this, you need to follow the Feng Shui tips and guidelines laid down for a receptive main door. There are a number of considerations like the material of the door, the colour of the door and the direction it is facing. These parameters are to be considered and set right. In case the door of your house is facing south, you need to paint it according to the element of the same direction.The element of South is fire, so paint the door red, orange, purple, strong pink, etc. You can also use green and brown colours associated with the element of wood, as it breeds fire. Another wise decision you need to make, along with the main door, is the protection of the back of the house. This will help the house to hold the energy it absorbs. For instance, the back of the house facing south will be towards north. Thus, you can paint the back door of your house in blue or black colour. This is because these colours are representative of Water element, ruling the North direction.
