Watch religion professor John S. Hawley on CBS News' "What They Believe," a program exploring beliefs and rituals of Hindus, Zoroastrians, Bahá'ís.
Prof. Hawley's research is focused on the religious life of north India and on the literature that it has spawned in the course of the last 500 years. His current major project—a book called India's Real Religion: The Idea of the Bhakti Movement—is devoted to deconstructing and reconstructing one of the principal ways in which Indians have told their religious history. Its focus: bhakti, the religion of song, of radical engagement, and of the heart.
