翻譯名義集 4.38

4.38

【婆蹉】（翻犢）【富羅】翻子。上古有僊，染犢生子，自後種姓，皆名犢子。此部計我，非是即蘊，亦不離蘊，而有實我。律本不來。《大集》云：「皆說有我，不說空相，猶如小兒，是故名為婆蹉富羅。」

[Vatsa] (translates as "calf"); [putra] (translates as "son"). In ancient times there was an immortal who consorted with a calf and gave birth to a son; from then on the lineage was called Vātsīputrīya. This school posits a self that is neither identical to the aggregates nor separate from the aggregates, yet is a real self. Its vinaya text did not come [to China]. The Daji jing says: "They all state that there is a self, and do not speak of the mark of emptiness, like small children; therefore they are named Vātsīputrīya."
