大般涅槃經集解 7.122

7.122

案道生曰：應說常也。僧亮曰：既以無我為倒，應以八自在為治，故云應服乳也。是大妄語者，無我者旨在生死，而云一切，是則妄語也。顛倒煩惱能燒眾生，取譬患熱也。法瑤曰：本以無常之火焚燒生死，而以濫執佛地，病之甚者，故云患熱也。僧宗曰：無常倒心虛而不實，以謬起故，應云虛熱。真常之解清涼真實，故云應服乳也。

Daosheng comments: Permanence ought to be expounded. Sengliang says: Since regarding non-self was an inversion, the eight sovereign powers should be used as a remedy; hence it says 'milk should be taken'. As for 'this is a great lie': the purpose of non-self lay in saṃsāra, but saying 'all' is a lie. Inverted afflictions are able to burn sentient beings, taking the metaphor of suffering from heat. Fayao says: Originally, the fire of impermanence was used to burn saṃsāra, but indiscriminately applying it to the Buddha-ground was a graver illness; hence it is said, 'suffers from heat'. Sengzong says: The inverted mind of impermanence is hollow and unreal, and because it arises from error, it should be called hollow heat. The understanding of true permanence is cool, pure, and real; hence it is said, 'milk should be taken'.
