述曰：由取無漏淨相故相觀多行，未能多時住無相觀，即後得智作有相淨觀也，雖作無相少時能故。《解深密》云「現前觀察行流轉愚」，言現前者，觀現前有漏法染也。

The Commentary states: Because one grasps at the pure marks of the untainted, mark-based contemplations frequently occur, and one is not yet able to abide for a long time in markless contemplation; that is, the pṛṣṭhalabdha-jñāna engages in mark-bearing pure contemplation, and although it engages in the markless, it is capable of doing so for only a short time. The Saṃdhinirmocana speaks of the 'delusion of directly observing the transmigration of conditioned factors'; saying 'directly' means contemplating the defilement of present, manifest sāsrava dharmas.
