A personal journey or spiritual quest remains an integral part of the human race. In olden divs, people came from the West to learn from Nalanda University. Modern technological inventions such as airplanes, harnessing the power of magnetic waves, etc. have their seeds in Vedic literatures, presented by leading Rishis such as Gautama and others. To make the best use of this human life is to know the root of everything that exists in the manifest world.
