Vastu is one of the oldest literatures available in the world and is part of ‘Vedas’. It is useful while selecting a plot, constructing a house or any establishment and during carrying out any renovations or doing any expansions and restructuring of the present construction. Vastu aligns the home or any construction with the subtle principles of earth gravity, magnetic field and effect of celestial bodies. As the proper alignment channelizes the energies and one start getting the power from nature in a natural way. Vastu forbids the demolition of any present construction if it has any flaw in it. It prescribes the measures to remove these flaws by proper alignment of the main door and removing any ‘Vedha” or obstruction to it, as main door is very important in both Vastu and Fengshui. The other drawbacks can be removed with the help of ‘Yantras’, interior planning and placement of gadgets which helps in harnessing the proper energy flow and positivity. Vastu creates harmony and balance between five elements i.e, earth, water, air, fire and space.
In Fengshui the door is considered the mouth through which “Chi” flows. Because according to Chinese people, the Chi which flows through the house has a deep connection with the Chi flowing inside the occupants. Balancing between these two is the ultimate motive of Fengshui. The shape of a house is given due importance in Fengshui and its placement on a height along with a water body flowing smoothly from North to South direction in front of it is the best thing to happen. According to another theory, in all the four directions, four animals exists which guard this position of house. These four animals are black tortoise in North, Phoenix in South, White tiger in the West and Dragon in the East. To understand Fengshui, Pa Kua is the most important symbol of Fengshui. It symbolises eight directions of the compass represented on the Pa Kua, with South always placed at the top. Each side of it corresponds to a particular direction and is deemed to represent a specific kind of luck and this luck is always expressed in terms of particular aspiration. These aspirations can be energized by use of other Fengshui methods. These eight aspirations are 1- Career, 2- Knowledge, 3- Family, 4- Wealth, 5- Fame, 6- marriage, 7- Children, 8- Helpful people. Its usage decides the placement of a room for a particular member of the family and by placement of a compass on the entrance of each room decides the directions. The other important concept is of Yin and Yang which represent negative and positive energies respectively which govern human existence. Both in ‘Taoism’ and ‘Confucianism’ these are represented by two interlocked curved shapes within a circle, one white and one black with a spot of the contrasting color within the head of each. There is a division of everything under the heaven in these two parts symbolising Sun and moon. Chinese believes that in order to get good Chi there should be a balance between these two forces so that one can lead a peaceful and satisfied life.
