Basava spread social awareness through his poetry known as Vachanaas. These are rational and progressive social thoughts coupled with established perception of God in Hindu society. "Brahminical thought" interpret the Vachanaas as essence of Vedic knowledge while attempting to explain the social revolution, Basava was able to bring in. But this theory, however, fails to explain why other well known religious leaders like Shankaracharya and Madhwacharya, who were very well acquainted with Vedic knowledge did not address the issues, that Basava did in later part of the history in 12th century. Basava, like Gautama Buddha, did not preach people the intricate aspects of spirituality; but, he taught people how to live happily in a rational social order later came to be known as Sharana movement.

Basava fought against the inhuman practice of caste system, which discriminated people based on their birth, and certain rituals in Hinduism. He spread social awareness through his poetry, popularly known as Vachanaas. These are rational and progressive social thoughts coupled with established perception of God in Hindu society.
