Abhinava on knowledge and ignorance

iha jñānaṃ mokṣakāraṇaṃ bandhanimittasya ajñānasya virodhakatvāt dvividhaṃ ca ajñānaṃ buddhigataṃ pauruṣaṃ ca tatra buddhigatam aniścayasvabhāvaṃ viparītaniścayātmakaṃ ca /

Here the knowledge is the cause of liberation because is being the opponent of ignorance which is the reason of bondage and the ignorance is twofold: in the intellect and humane; there, the intellectual is of nature of non-knowledge (a-niścaya) and wrong/reversed knowledge(viparīta-niścaya).

pauruṣaṃ tu vikalpasvabhāvaṃ saṃkucitaprathātmakaṃ tad eva ca mūlakāraṇaṃ saṃsārasya iti vakṣyāmo malanirṇaye /

But the humane [ignorance] is of nature of imagination and contracted expansion; "and this one is the root cause of transmigration (saṃsāra)" we will say in the discussion on impurity.
