Gandhi believed that Buddhism, Jainism and Sikhism were traditions of Hinduism, with a shared history, rites and ideas. At other times, he acknowledged that he knew little about Buddhism other than his reading of Edwin Arnold's book on it. Based on that book, he considered Buddhism to be a reform movement and the Buddha to be a Hindu.[81] He stated he knew Jainism much more, and he credited Jains to have profoundly influenced him.
