Vastushastra is an ancient building science which covers the philosophy and theory of Architectural works to construct any building and as well as living style of people. Vastushastra is based on various natural energies which are available in atmosphere like -

Solar Energy from Sun
Lunar Energy from Moon
Earth Energy
Sky Energy
Electric Energy
Magnetic Energy
Thermal Energy
Wind Energy

Cosmic Energy

Right utilization of such energies gives us pleasure peace, prosperity and money etc in our life. Now a days we are having National Building code, which gives us certain regulations to construct building, whereas in past our ancestors were having Vastu Shastra as a religious & rigourics code. As per Shastra Vastu Purush is God of building science, hence let us pray.

Hey Vastu Dev ! Saluting. You always lies on earth and fulfills our houses with happiness and property, as Meru hills are place for all gods, you bless us that all gods including Brahma stays at my house statically.

Vastu can be used for every room, every house, every temple, every shop industry, town planning , tour, cities and even for earth. Vastu can be used for micro as well as for macro level.
