The human aura is a multi-layered energy field that surrounds the human body. Each layer is represented by different colors and contains important information about our physical, mental, emotional and spiritual health. Whatever we do to our body, whether good or bad, will manifest in our aura.

Vastu Shastra is not a belief or a superstition. It is pure science of the Cosmos. There is nothing to be 'believed' or 'worshiped'. Every principle and technique has a scientific explanation behind it; it can be observed regardless of religion or beliefs.

Cosmic radiation from planets is a very interesting field of research. The harmful cosmic radiations from space are mostly filtered as they enter the earth's atmosphere and pass through it. The hazardous unfiltered cosmic radiations interact with human beings. Dwelling places constructed according to Vastu principles will give maximum positive cosmic energy. Interaction with this positive cosmic energy improves the health of the occupants of the house and results in a better aura. By studying this modified aura, the health of a person can be better understood and also predicted.
