金光明最勝王經疏 4.108

4.108

即欲背生死愚。希趣涅槃者，即欣涅槃愚。不能了生死涅槃真體無別故，故有欣厭。此即於下乘般涅槃障，又作勝菩提分觀，未能證得無差別如，為五地障。前後說障，皆準此知。由於五地作四諦觀，真俗二智合令雙行。由能證得無差別如，能證之智名無差別道。故《成唯識論》云「彼障五地無差別道，入五地時便能永斷，故能除彼。」

This is the folly of desiring to turn away from saṃsāra. 'Hoping to head toward nirvāṇa' is the folly of seeking nirvāṇa with longing. Because one cannot comprehend that the true reality of saṃsāra and nirvāṇa is not different, longing and revulsion arise. This is the obstacle of parinirvāṇa in the lower vehicle; furthermore, practicing superior contemplation of the factors of bodhi, one has not yet realized the tathatā of non-differentiation, which constitutes the obstacle to the fifth ground. What was explained before and after regarding obstacles should all be understood in this way. Because on the fifth ground one cultivates the contemplation of the four noble truths, one unites the two wisdoms—the real and the conventional—making them operate together. Because one can realize the tathatā of non-differentiation, the wisdom that realizes it is called the path of non-differentiation. Therefore the Cheng weishi lun says: 'They obstruct the path of non-differentiation of the fifth ground; upon entering the fifth ground, one can sever them forever, and thus can eliminate them.'
