注大乘入楞伽經 3.143

3.143

言圓成自性無別自體，但於緣起自性，離名相事相妄想分別，自覺聖智所證如如，此即圓成自性法身實體，如來藏性清淨真心也。是故須假如實方便，離念觀察，方能悟入。故《摩訶衍論》云「圓成實自性，應知宣說四清淨法：一、自性清淨，謂真如實際勝義法界；二、離垢清淨，謂即此離一切障垢；三、得此道清淨，謂一切波羅密多菩提分法；四、生此境清淨，謂最上乘妙正法教。如是四法，總攝一切清淨諸法，無有遺餘。」

This means that pariniṣpannasvabhāva has no separate substance of its own; it is simply within paratantrasvabhāva, freed from the parikalpa and vikalpa of nāmalakṣaṇa and phenomenal marks, the tathatā realized by noble wisdom within oneself—this is the real substance of the dharmakāya that is pariniṣpannasvabhāva, the pure, true mind of the tathāgatagarbha nature. Therefore, one must rely on expedient means conforming to reality, observing free from conceptual thought, in order to be able to awaken and enter it. Hence the Mahāyāna Treatise states: "Concerning pariniṣpannasvabhāva, one should know that four pure dharmas are expounded: first, purity of intrinsic nature, which refers to tathatā, the limit of reality, the paramārtha dharmadhātu; second, purity free from defilement, which refers to this very nature being freed from all hindrances and defilements; third, purity of attaining this path, which refers to all pāramitās and bodhipakṣa dharmas; fourth, purity of generating this realm, which refers to the sublime true Dharma teaching of the supreme vehicle. These four dharmas completely encompass all pure dharmas without remainder."
