"Before the coming of the Aryans […] the Tamils believed that any taking of life was dangerous, as it released the spirits of the things that were killed. Likewise, all who dealt with the dead or with dead substances from the body were considered to be charged with the power of death and were thought to be dangerous. Thus, long before the coming of the Aryans with their notion of varna, the Tamils had groups that were considered low and dangerous and with whom contact was closely regulated."
