俱舍論疏 26.55

26.55

論「如是二種至不緣想等」，此明取別境也。若無漏、若有漏二種他心，皆唯但緣一法為境。

On the Śāstra's statement: "These two kinds […] does not take ideation and so forth as object": this explains that it apprehends a distinct object. Both kinds of knowledge of another's mind—whether untainted or tainted—take solely a single phenomenon as their object.
