"The Lord is present in everyone's heart, and He gives the living entity intelligence. According to the desires of the living entity, the Lord makes him remember or forget. If the living entity is demoniac and wants to forget the Supreme Personality of Godhead, the Lord gives him the intelligence to be able to forget the Supreme Lord forever. Similarly, when a devotee wants to serve the Supreme Lord, the Lord, as Paramātmā, gives the devotee the intelligence to make progress in devotional service. The Lord directly witnesses our activities and experiences our desires. The Supreme Lord gives us the facilities to act in the way we wish."
(Śrīmad-Bhāgavatam 4.30.26, Purport)
