瑜伽論記 22.107

22.107

前中，師之名義，略有十六句，景師云：能獎、勝獎、至獎三義者，文通於三師，能導、勝導、至導三義，亦通三師。泰師云：根本和上闍梨名第一伴，若說菩薩等誓法，更為一切眾生作和上闍梨，故名第二伴。經中有此別名故通之。

In the former, regarding the name and meaning of the teacher, there are briefly sixteen phrases. Master Jing says: "The three meanings of being able to encourage, supremely encouraging, and ultimately encouraging apply throughout the text to the three teachers; the three meanings of being able to guide, supremely guiding, and ultimately guiding also apply to the three teachers." Master Tai says: "The root upādhyāya and ācārya are called the first companions; if one speaks of the vow practices of the bodhisattva and so forth, becoming an upādhyāya and ācārya further for all sentient beings, they are called the second companions. The sūtra contains these distinctive names, hence they are explained."
