Mahāsammata is translated here as "Great Equal Consent"—the grand assembly having an equal inclination of mind, mutually established him as their sovereign, appointing him as the arbiter. He is also named Kṣetrasvāmin, which is translated here as "Lord of the Fields." The Kṣatriyas are named as his descendants; he is indeed the great-great-grandfather of Śākya[muni], which is why Kṣatriyas are called the lineage of royal clan. Brāhmaṇas are called the lineage of pure conduct, claiming to be descendants of the Brahmā King. Vaiśyas are called the lineage of sitting and taking, sitting and taking profit. Śūdras are called the lineage of tilling the fields.
