瑜伽論記 15.216

15.216

五云：世俗攝，通世出世者，此是對無分別智，故說後智名世俗智，體是無漏名為出世世，緣世事起復名世間。由此義故，通世出世。

The fifth says: "Subsumed under the worldly, applying to both the worldly and supramundane": this is in contrast to non-conceptual knowledge; hence the subsequent knowledge is called worldly knowledge. Its essence is taintless, so it is called supramundane; arising by observing worldly matters, it is again called worldly. By virtue of this meaning, it applies to both the worldly and the supramundane.
