4.74

二、別申大乘經者，如《十地論》別申《華嚴經》別、圓兩教，《大智度論》別申《摩訶般若經》通、別、圓三教，應有別申《大集方等》及此經論，不來此土，《金剛般若論》別申《金剛般若經》，《法華論》別申《法華經》一圓教，《涅槃論》別申《涅槃經》四教五味，論度此不盡。如此等諸論申經，即是申觀心等諸經，令分明也。

Second, treatises specifically expounding Mahāyāna sūtras: for example, the Daśabhūmika Śāstra specifically expounds the two teachings—distinctive and perfect—of the Avataṃsaka Sūtra; the Mahāprajñāpāramitopadeśa specifically expounds the three teachings—shared, distinctive, and perfect—of the Mahāprajñāpāramitā Sūtra; there ought to be treatises specifically expounding the Mahāsaṃnipāta Vaipulya and this sūtra, but they have not arrived in this land; the Vajracchedikā-prajñāpāramitopadeśa specifically expounds the Vajracchedikā-prajñāpāramitā Sūtra; the Saddharmapuṇḍarīkopadeśa specifically expounds the single perfect teaching of the Lotus Sūtra; the Nirvāṇa treatise specifically expounds the four teachings and five flavors of the Nirvāṇa Sūtra, but the treatises translated here are incomplete. When these treatises expound sūtras in this manner, they are precisely expounding the sūtras of contemplating the mind and so forth, making them distinct and clear.
