瑜伽論記 16.170

16.170

基云：前文意未知根是九根分故憂唯欲繫。今此文意如對法，初二無漏根為體，取十根，故憂通，二緣三。初二無漏是學以三種為義，俱知是無學以三種為義。

Ji says: The intention of the former text was that the faculty of unknown-to-be-known is a portion of nine faculties, and therefore grief was bound only to desire. The intention of this current text is like that of the Abhidharma: taking the first two taintless faculties as their substance, ten faculties are taken; therefore grief is open, and two take the three as their object. The first two taintless ones are in training and have the three kinds as their object; the faculty of having known is beyond training and has the three kinds as their object.
