成唯識論述記 10.278

10.278

述曰：文中有四：一、出體；二、辨相；三、即愚；四、顯有。此初也。《十地》云「於無相有行障」，世親《攝論》云「於無相作行」，義意大同。餘文易了。

The Commentary states: There are four parts in the text: first, presenting the essence; second, distinguishing the marks; third, identifying the delusion; fourth, showing its presence. This is the first. The Daśabhūmika calls it the 'obstacle of having activity within the markless'; Vasubandhu's Mahāyānasaṃgraha calls it 'performing activity within the markless'; their conceptual intent is largely identical. The rest of the text is readily understood.
