後緣無相定，非擇滅為靜者，釋重無相也。無相無相即緣無學無相三摩地非擇滅為境，以無漏法無擇滅故，觀前無相非擇滅故，於無相上復更無相，名無相無相。觀非擇滅，但取靜相，非滅妙離，濫非常滅，不作滅相，以非擇滅是無記性故。不作妙相，非離繫果，不作離相。

'The last takes the signless concentration as object, regarding non-analytical cessation as tranquil' explains the double signlessness. Signlessness of signlessness takes as its sphere the non-analytical cessation of the aśaikṣa samādhi of signlessness, because uncontaminated phenomena have no analytical cessation; because it contemplates the non-analytical cessation of the preceding signlessness, there is further signlessness upon signlessness, called 'signlessness of signlessness'. Contemplating non-analytical cessation, it grasps only the aspect of tranquillity; it does not [grasp] cessation, excellence, or escape: to avoid confusing it with the cessation of impermanence, it does not adopt the aspect of cessation; because non-analytical cessation is by nature morally indeterminate, it does not adopt the aspect of excellence; because it is not the fruit of disjunction, it does not adopt the aspect of escape.
