首楞嚴義疏注經 3.76

3.76

'Gathers' means collects. 'Within' is like the interior. 'Inhaling' and 'seizing' both mean grasping. Due to the objects of arising and cessation, the internal aware and knowing nature is brought forth and gathered; this awareness and knowing constantly grasps arising and cessation, discriminating internally, unlike the previous five which illuminate external sense objects; therefore they are called 'internal dusts', because the mind faculty conditions internally and does not condition externally, which is the 'gathering of conditions wavering within' in the preceding text.
