In Sri Venkatachala Mahathyam Lord Brahma became a cow, Lord Siva became a Calf and Sri Lakshmi became a Yadava maid and both the cow and calf were sold to Chola king by Sri Lakshmi in a bid to provide milk to meditating Srinivasa in Venkatachalam. There also He protected the cow from the curse of its herdsman.
Sri Venkateswara Gosamrakshana Trust is established for protecting the cow and emphasizing the spiritual importance of the cow apart from its economic aspect. The divine cow protects the universe by embodying the deities, Gods and Goddesses of Hindu Religion. Since the ancient time cows role in Agricultural and Human Health has been appreciated, scientific knowledge base confirms the ancient’s understanding. It is time to take firm action to educate or re-educate people / society about the role of cow in Agriculture / animal Health care and Human Health, besides ecological significance.
Further, TTD has initiated Gosamrakshana and cow wealth development activities in large scale, by establishing an extension unit of S.V.Gosamrakshana Shala and named as Sri Venkateswara Gosamrakshana Research Centre aimed as model centre of excellence for cow wealth development to be developed as a role model for emulation by rest of the humanity at large and be the torch bearer in generating and leading the enlightened public opinion on the wisdom for realigning the society policies and approaches in favour of sacred cow.
