Nowadays there is a lot of talk about Vastu Shastra in all the towns and villages. Being a science related to construction of dwelling houses, temples, factories, commercial places etc. it is called Vastu Shastra. This science is based on the 5 elements called Earth, Water, Fire, Air and Sky (Prithvi, Aapah, Tejah, Vayuh, Aakasa) otherwise known as Pancha Maha Bhutah, without which no living being on earth can survive. If we can see and feel the presence of these elements and if you can see and feel the east solar rays and north magnetic rays, this can be called a science.
