大般涅槃經集解 5.70

5.70

案道生曰：邪心內昏，譬臥寐也。僧亮曰：乘惑受報，非本所期，曰寄止。流遁既久，遂失常解，說佛為無常，譬眠寐也。曇濟曰：生死不可久處，為寄也。智秀曰：雖有微解，惑障慧眼，暫忘所懷，如昏寐也。

Daosheng comments: The wrong mind is dark within, allegorized as being asleep. Sengliang says: Borne by delusion to receive retribution, not what was originally expected, is called 'lodging.' Having drifted for a long time, one ultimately loses the understanding of permanence and declares the Buddha to be impermanent, allegorized as being asleep. Tanji says: Saṃsāra cannot be dwelt in for long, hence 'lodging.' Zhixiu says: Although having slight understanding, delusion obstructs the eye of wisdom, temporarily forgetting what one harbored, like being in a dim sleep.
