成唯識論述記 4.644

4.644

述曰：量云：汝宗求緣涅槃心應起散心；求緣寂靜故；如滅定前心。以此返彼亦得可知，下破本計。

The Commentary states: The syllogism is: In your school, a mind that seeks and focuses on nirvāṇa should give rise to a distracted mind, because it seeks and focuses on tranquility, like the mind prior to the cessation attainment. Using this to turn against him can also be understood. Below, his original assertion is refuted.
