維摩經玄疏 4.74

4.74

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.
