Vaastu Shastras professing the ancient Indian Science and Technology of design and construction of structures and of Town Planning, that have been in vogue from very early times, are not mere building codes or construction manuals, as generally assumed and propagated by the scholars. They are but Shastras replete with technological material and measures, based on unique Science of Energy and Matter, Time and Space & Space and Spatial Form, so far not recorded in the history of the land of their origin. This science has escaped the notice of all, over the centuries.
This unique and supreme science of India lay dormant during all the alien rules, but today it is reemerging spectacularly. This science succinctly called the science of Time and Space, Space and Spatial Forms, is actually the science of subtle energy turning itself into gross energy or embodied energy. As applied in the field of Architecture (Vaastu) and Sculpture (Shilpa), the same subtle energy turns into material forms such as buildings, temples, imagic forms etc. All these forms are not religious but spiritual, and hence universal. But each religion has made these forms sectarian with their symbols superposed on them.
The Indian science of Vastu and Vaastu has recognised that the universe is subject to a mathematical formula and architecture is yet another manifestation of this formula – "architecture is the supreme achievement of mathematics", says Mayan, the legendary architect cum scientist. This is the science underlying technological principles and processes in the domain of traditional art and architecture of Vaastu Shastras. The Vaastu Shastras have evolved the temple structure as form of God 'Praasadam Purusham Matva Poojayet Mantra Vittamaha'- Shilpa Ratna and hence it is worship worthy. The yardstick used to give form to consciousness, that is into visual and aural forms is governed by the science of Time and Space using Light and Sound as raw materials. This is the basic science of all Vaastu Shastras.
