 In Hinduism, based on the principle of "ahimsa", any human or animal sacrifice is forbidden.In the 19th and 20th centuries, prominent figures of Indian spirituality such as Swami Vivekananda, Ramana Maharshi, Swami Sivananda, and A.C. Bhaktivedanta Swami emphasised the importance of ahimsa.In the city of Altamira, State of Pará, several children were raped, with their genitalia mutilated for what appear to be ritual purposes, and then stabbed to death, between 1989 and 1993.
