大般涅槃經集解 19.6

19.6

案僧亮曰：藥譬佛性，甜譬常樂也。僧宗曰：見佛性者，治生死之病，譬之藥也。樂味者，味體非樂，能生人樂；佛性非樂，會之者出苦，故譬之樂味也。極甜者，甜味則為人所嗜；佛性之理，有識所甘，喻之甜味也。智秀曰：一味者，佛性之理，無生滅之異也。

Sengliang comments: The medicine compares to the buddhadhātu; sweet compares to permanence and bliss. Sengzong comments: Seeing the buddhadhātu cures the sickness of birth and death, which is compared to the medicine. As for 'flavor of bliss,' the substance of flavor is not bliss, but it can generate bliss in people; the buddhadhātu is not bliss, but one who accords with it transcends suffering, hence it is compared to the flavor of bliss. As for 'extremely sweet,' sweet flavor is craved by people; the principle of the buddhadhātu is relished by conscious beings, so it is compared to sweet flavor. Zhixiu comments: 'Single flavor' means that the principle of the buddhadhātu has no difference between arising and ceasing.
