(design) of Vastu Purusha
This figure depicts the Vaastu Purusha Mandala, wherein the Vaastu Purusha lays on the ground with hi head facing the ground. He is surrounded by the deities from the directions and in the center is Lord Brahma.
Whether this legend is absolutely true, or partially, the laws of Vaastu Shastra are not mythological stories. They are in fact authentic and reliable experiences of people and have stood the test of time for thousands of years now.
