God is sentient and can hear the prayers and fulfill the desires of the devotee. Therefore, He is sac-cid-ananda-vigraha (Brahma Samhita 5.1), the form of bliss, knowledge and eternity.
Srimad Bhagavatam 3.21.19,
Godhead is light. Nescience is darkness. Where there is Godhead there is no nescience.
Srimad Bhagavatam 7.8.24,
This is the divinity of the Personality of Godhead: He is not affected by the qualities of material nature, even though he is in contact with them. Similarly, the devotees who have taken shelter of the Lord do not become influenced by the material qualities.
Krishna and pure devotees see through the substance, not the maya the world sees through.
