瑜伽論記 4.172

4.172

文中既約定地明七作意，謂從初靜慮乃至非想，何須別簡欲界緣法緣義，故不言攝一分等，而言了相為聞思雜者，此為欲界聞思之所間，以未至定隣近欲界故或出或入與聞雜，從此已上超越聞思一向修相故。

Since the text explains the seven mental applications in terms of the concentrated stage, namely from the first dhyāna up to neither-perception-nor-non-perception, what need is there to separately exclude focusing on dharmas and focusing on meaning in the desire realm? Hence it does not say 'subsumes a portion', and so on. As for saying that 'discerning characteristics is mixed with listening and contemplation', this means it is interspersed with the listening and contemplation of the desire realm, because the unarrived concentration (anāgamya-samādhi) is adjacent to the desire realm, and whether emerging or entering, it is mixed with listening; from this stage upward, one transcends listening and contemplation and has exclusively the characteristics of cultivation.
