Patanjali Yoga Sutra 1.41
Just as the naturally pure crystal assumes shapes and colors of objects placed near it, so the Yogi’s mind with its totally weakened modifications, becomes clear and balanced and attains the state devoid of differentiation between knower, knowable and knowledge. This culmination of meditation is Samadhi.
Siva Sutra Svacchanda Tantra
Bondage is just differentiated knowledge. It is experiencing the objects of the world as separate from god consciousness. Here, you think that God consciousness is pure and consciousness in worldly life is impure. You must quite experiencing these kinds of bondage and focus your mind inward toward pure God consciousness. When you abandon this experience of bondage and direct your mind toward God consciousness, experiencing only yourself, that is known as the pervasion of God consciousness, the pervasion of the Self.
