Vastu extends into the realm of occultism!
Vastu is ancient science of living! The word Vaastu is derived from the root ‘Vas’ which means ‘to reside’.
It is not an equivalent of the word architecture. Vastu is architecture and much more. While architecture is the science, art or profession of designing and constructing build- ings etc., the definition of Vastu extend into the realm of occultism.
Vastu means dwelling of Humans and Gods in the original Sanskrit literature.
If construction is not according to the principles of “VASTU” then thinking and action of the people dwelling or working in these places is not harmonious and evolutionary; leading to disorder & illness.
On the contrary, if the laws of nature which are elaborated and incorporated in the science of Vastu are followed, then all the Divine powers support the thinking and action of the people associated with such concerns.
Building a house in ancient India was not only a house-craft but also a sacred ceremony and the house was considered a living organism. The spirit of the house was called the Vastu Purusha and different cardinal directions and sectors were assigned to different Gods like Brahma, Ishwara, Agni, Varan, Wind, Yam and Demon, since the waves flowing in a particular direction have a specific influence.
