瑜伽論記 14.84

14.84

今依此論釋家三解。一云，但須和上清淨大眾不須清淨，清淨戒屬上故。二云要須大眾清淨不須和上清淨，住清淨戒屬下故。三云：此文長讀，若大眾及和上俱清淨方得與人受具戒，若十若五眾中，必須有一解律儀許知戒相羯摩是非所以和上性遮俱持，闍梨持性戒遮不定，要須迅辨令他生善故。

Now, based on this treatise, the commentators offer three explanations. The first says that only the preceptor (upādhyāya) must be pure, while the assembly need not be pure, because [the phrase] 'pure precepts' belongs with the former. The second says that the assembly must be pure while the preceptor need not be pure, because [the phrase] 'dwelling in pure precepts' belongs with the latter. The third says: this text should be read continuously [such that] only if both the assembly and the preceptor are pure can they confer full ordination upon someone; and among the assembly of ten or five, there must be one who understands the monastic disciplinary code (śīla-saṃvara) and is permitted to know the characteristics of the precepts and what is right and wrong in karmavācanā procedures; for this reason, the preceptor observes both inherent and proscriptive [rules], whereas for the ācārya observing inherent [rules is required while] proscriptive [rules are] undetermined, and he must be quick-witted so as to cause others to produce wholesome [qualities].
