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 (15[1])gotra (15[1])lineages based on their (15[1])descent from seven rishis. Eight-year-old boys from this (15[1])group become ‘twice (15[3])born’ by receiving a sacred (15[1])yellow (15[2])thread in the Upanayana (15[2])ceremony. One of these (15[1])people called a purohita performs (*) yajna ceremonies by sacrificing offerings to a ritual fire. These people are forbidden from killing (10[1])animals and traveling (10[1]-5[1])overseas. This varna was created from the mouth of Purusha in a hymn from the Vedas, which this (10[1])caste had a monopoly on teaching. For 10 points, name this priestly (10[1])caste in Hinduism. (10[3])■END■
