For more than a decade, Doniger’s scholarship has been under attack by conservative Hindu groups who feel that her work misrepresents and insults their religion; last month, her eight-hundred-page book “The Hindus: An Alternative History” was pulled from bookstores in India. Her latest book, “On Hinduism,” which is in its second printing in India, is a collection of essays and lectures addressing contemporary and historic debates surrounding the religion, from the ethical implications of Hindu cosmologies to gender inversions in the Kama Sutra. Dinanath Batra, the man who filed the suit against “The Hindus,” has said that he intends to take aim at “On Hinduism” next.
