Those among them who were learned and pious, whose living was better in every way than the others, grouped themselves, and called themselves Brahmans, whose part of work was study, scientific investigation, music, poetry; and priesthood was their right. They taught people as teachers. At the wedding ceremonies and at births and deaths they took charge of the ceremonies with their religious rite. Their life was as the life of a hermit. The difference was that they married among their own people. Their living only depended upon Bhiksha -- free will offerings.
