注維摩詰經 2.73

2.73

肇曰：天竺多諸異道，各言己勝，故其國別立論堂，欲辯其優劣。欲明己道者，則聲鼓集眾，詣堂求論，勝者為師、負者為資。淨名既升此堂攝伏外道，然後導以大乘，為其師也。

[Seng]zhao says: In India there are many heterodox traditions, each claiming its own superiority; thus that country establishes separate debate halls to discern their merits and flaws. Whoever wishes to clarify his own way beats a drum to gather the multitude and approaches the hall to challenge debate; the victor becomes the master, and the defeated becomes the disciple. Pure Name mounted this hall to subdue the non-Buddhists, and only then guided them with the Mahāyāna, becoming their master.
