The Naiyyayikas believe that the bondage of the world is due to false knowledge, which can be removed by constantly thinking of its opposite (pratipakshabhavana), namely, the true knowledge. So the opening aphorism of the  states that only the true knowledge lead to niḥśreyasa (liberation). But the Nyāya school also maintains that the Gods grace is essential for obtaining true knowledge. Jayanta, in his Nyayamanjari' describes salvation as a passive stage of self in its natural purity, unassociated with pleasure, pain, knowledge and willingness.
