Pyramid Vastu (PyraVastu) is the application of Vastu principles through pyramid space.
The five elements of material nature, Earth, Water, Fire, Wind, and Space govern us. Harmony between these elements in our body and our environment brings about peace and balance within us. Because physical existence and change also affect and define space, by manipulating space the behavior of the five elements are influenced. Vastu and Feng Shui are particularly important within an enclosed space because the space affects the energy flow.
When there are boundaries, the enclosed space is a bounded space. The bounded space has internal effects and effects in harmony with the outer space. Its own working depends upon the geometry of the boundary. Pyramid yantra uses a technique to take advantage of the properties of bounded space. Multiplication increases the effect of bounded spaces. The power of pyramid yantra is based on the permutation, combination, and interaction of such known multiple spaces. So multiple space is one of the most important factors in PyraVastu.
A Pyramid Yantra uses 91 interactive chambers, through the power generation formula 9x9. This 9 times 9 law is used in astrology (9 planets), numerology (9 numbers), Vastu and Feng Shui (grid of 9), and in traditional Islamic, Chinese, and Hindu yantras. The power generation formula of Pyramid Yantra is used through an inner layer of 81 micro chambers (9 chambers along a side with 9 chambers along the other side and the inner space filled with micro chambers), a layer of 9 middle chambers surrounding the micro chambers, and one top outer chamber.
The pyramid yantra is a miniature version of a pyramid. It can be a single pyramid or a set (usually in multiples of nine) of pyramids arranged either horizontally or vertically (one above another), called 'multier'.
