Vaastu is the science of direction that combines all the five elements of nature and balances them with man and materials. It is all about the interaction of various forms of best effect on a living person. It aims to create a subtle conducive atmosphere in a structure in which we can bring the best in ourselves, thereby paving the way for enhanced health, wealth, prosperity and happiness in an enlightened environment. Like any other science, vaastu is universal, rational, practical and utilitarian. It is not a religion but a science.
The principle laid down in Vastu Shastra were formulated keeping in view, the cosmic influence of the Sun, its light and heat, solar energy, directions of wind, the moon position, the earth's magnetic field and the influence of cosmos on our planet. The system is an admixture of science of directions, astronomy and astrology.
What is Vastu Shastra? - Vaastu Shastra, Vastu Shastra based on Ancient Science, Indian Vastu Shastra according to The directions - The importance of orientation of a building is not only for saving energy but also to have a better healthy house design, which not only gives comfortable living but also gives good health, prosperity and wealth to the house owners/occupiers and these families. There lies a co-relation between the rotational scenario of the planets and the house design and their different directions with respect of NORTH. The building of any type and its construction meets the purpose if proper orientation has been given using suitable local building material. It increases not only its life span but also improves the condition of occupants. There are instances where buildings are not planned according to required local orientation were lost or deteriorated much faster then the buildings having built with proper studies of orientation. The proper orientation means the proper knowledge of all the eight directions. It is a common knowledge that the direction from where the Sun arises is known as East (Poorva) and where it sets as West (Paschim) and when one faces the East direction, towards one's left is North (Uttara) and towards one's right is South (Dakshina). The corner where two directions meet obviously is more significant since it combines the forces emanating from both the directions. According to Shastras if we worship, revere and respect the Lords of these eight directions, they will shower on us their blessings and benefits. Let us examine their importance according to scriptures.
