大般涅槃經集解 33.14

33.14

案僧宗曰：非滅生滅想者，謂計非想為涅槃果，八禪為因也。寶亮曰：釋第六一因之實。

Sengzong states: Conceiving non-extinction to be extinction means positing neither-conception[-nor-non-conception] as the fruit of nirvāṇa and the eight dhyānas as the cause. Baoliang states: Explaining the sixth, the reality of the single cause.
