俱舍論記 10.114

10.114

「於中十五至皆通二種」者，明雜緣、不雜緣，於中十五名不雜緣，謂色等五，喜、憂、捨三各別緣故。三法近行通雜、不雜。若唯緣法及六內處，或總或別皆名不雜。或於此七隨緣多少兼於五外隨緣多少，或唯於五外隨緣多少，皆名雜緣。此中言法，通名法也，非唯法處。

Regarding "Among them, fifteen … all admit of both types": this clarifies mixed objects and unmixed objects. Among them, fifteen are called taking unmixed objects, meaning that the five, visible form and the rest, are separately taken as objects by the three: joy, grief, and equanimity. The three mental applications taking dharmas as objects admit of both mixed and unmixed. If they solely take dharmas and the six internal bases as objects, whether collectively or separately, all are called unmixed. Or if, relative to these seven, however many are taken as objects, combined with however many outside the five, or if they solely take however many outside the five as objects, all are called mixed objects. Here the word 'dharmas' generally names dharmas, not solely the dharma-base.
