He was one of the founders of modern Indian thoughts. He brought new thinking and perspective about the Vedas and worked against idolatry and ritualistic worships. He championed universal brotherhood and gave a liberal perspective about Hinduism.
On the social front his Arya Samaj movement worked for equality of humankind and championed women empowerment. The Arya Samaj asked people to question rituals and beliefs that run contrary to common sense and logic. His book Satyarth Prakash is a study in comparative religion in order to test religion on the basis of rationality. His search for truth and his journey makes me proud.
