俱舍論疏 13.94

13.94

論「所引證中至故名無對」，釋第一證。經言第三無見無對者，謂定境界色非眼見故名無見，不障處所名為無對，非是無表。

On the treatise's statement, "Among the cited proofs ... therefore it is called unobstructed": this explains the first proof. When the discourse speaks of the third, invisible and unobstructed [matter], it refers to matter that is the domain of meditative concentration: because it is not seen by the eye, it is called invisible; because it does not obstruct spatial location, it is called unobstructed; it is not non-information.
