摩訶止觀 8.173

8.173

如是觀時，不叨上聖。又當安忍內外諸障令得無礙。若發似道，未是真解，勿生法愛。法愛不起，則任運無滯，自然流入清涼之地。是大乘十觀，得無量無漏清淨果報，獲得無上報，獲得自在業，深達罪福，究竟無染，故名「清淨即是法身」；反本還源，智照圓極，故名「無上即是報身」；垂形九道，普門示現，故名「自在即是應身」。如是三身即是大乘高廣，直至道場。餘如上說（云云）。

When contemplating in this way, do not lay false claim to the superior sagehood. Furthermore, one should patiently endure various internal and external hindrances so that one becomes free of obstruction. If semblance of the path arises, it is not yet true understanding; do not give rise to craving for the Dharma. When craving for the Dharma does not arise, then proceeding spontaneously without stagnation, one naturally flows into the realm of cool refreshingness. These are the ten contemplations of the Mahāyāna, obtaining immeasurable, uncontaminated, pure fruition and retribution, obtaining the unsurpassable retribution, and obtaining sovereign karma. Profoundly penetrating sin and merit, ultimately without defilement, it is therefore called 'purity is precisely the dharmakāya'; returning to the origin and reverting to the source, prajñā-illumination being consummately perfect, it is therefore called 'unsurpassability is precisely the saṃbhogakāya'; manifesting forms in the nine destinies, appearing everywhere through universal gates, it is therefore called 'sovereignty is precisely the nirmāṇakāya.' These three bodies are precisely the lofty and broad Mahāyāna, leading straight to the bodhimaṇḍa. The rest is as described above (and so forth).
