 Such practices of human sacrifice were mostly replaced by animal sacrifice, or the self-infliction of wounds in religious ritual, by the 20th century.Grunfeld (1996) concludes that it cannot be ruled out that isolated instances of human sacrifice did survive in remote areas of Tibet until the mid-20th century, but they must have been rare enough to have left no more traces than the evidence cited above.In India, human sacrifice is mainly known as "Narabali".
