//Ancient India was a land of sages, saints and seers as well as a land of scholars and scientists. Rishis were the sages who built our great culture. They devoted their life, energy and experience for the welfare of people. They wrote Vedas - the manual of vibrations. Following this many field of science evolved in India. //

This is typical hindutva propaganda, where they claim that anything and everything originated from Vedic scriptures, which are for welfare of people.

Before buying into it, I would suggest the readers to review the works of Dr. Ambedkar such as Riddle In Hinduism. http://www.ambedkar.org/riddleinhinduism/
