大般涅槃經集解 5.40

5.40

案道生曰：眾結為病苦，生死為飢渴也。法瑤曰：內無家善、外無友護，是以為惡友眾病所加、飢渴所逼也。僧宗曰：無禪定之漿、又闕涅槃法食，故云飢渴。

Daosheng comments: The various fetters are the suffering of illness; saṃsāra is hunger and thirst. Fayao says: Internally lacking the goodness of one's home and externally lacking the protection of friends, one is therefore afflicted by bad companions and many diseases, and pressed by hunger and thirst. Sengzong says: Lacking the syrup of dhyāna-concentration and also deficient in the Dharma-food of nirvāṇa, it therefore says 'hunger and thirst.'
