瑜伽師地論略纂 1.115

1.115

摩訶三末多，此云大等意，大眾齊等意樂，共同立以為尊，稟成司契。亦名差摩塞縛彌，此云田主，諸剎帝利，稱此後也，即釋迦之高祖也，故剎帝利名王族種。婆羅門，云淨行種，稱梵王後。吠舍，云坐收種，坐而收利。戎達羅，云耕田種也。

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.
