One of these people is taught humbleness by a butcher in the Vyadha (15[1])Gita. Tamil communities of these people include the Iyers and (15[1])Iyengars. Historically, these people were split into seven gotra lineages based on their (15[1])descent from seven rishis. Eight-year-old boys from this group become ‘twice (15[2])born’ by receiving a sacred yellow thread in the Upanayana ceremony. One of these people called a purohita performs (*) yajna ceremonies by sacrificing offerings to a ritual fire. These people are forbidden from killing animals and traveling (-5[1])overseas. This varna was created from the mouth of Purusha in a hymn from the Vedas, which this caste had a monopoly on teaching. For 10 points, name this priestly caste in Hinduism. (10[1])■END■
