Remembrance, Forgetfulness and Knowledge

Krishna, as the Supersoul in everyone's heart, helps one to fulfill one's desires in this world. According to our aspirations, we require to forget some things (such as God if one is an atheist), we require to remember other things, and we need knowledge-Even the animals have instinctually based behaviour that coincides with the desires. This so called instinct is actually Krishna in the heart helping them to carry out their plans. Krishna knows the aspirations of all living entities. Krishna does this to give them facility to enjoy all of the varieties in this world. When the soul has finally realized the futility of attempting to enjoy separately from God, he turns to Krishna in the heart.

We have forgotten that we are part and parcels of Krishna, His eternal servants, because we want to pretend to be the "master of all we survey." Krishna, however, sends messengers (saints, sages, preachers) to us to remind us of who we are. Krishna says that to one who seeks Him, serving Him with devotion, He gives knowledge how to approach Him.2 When someone comes to full Krishna consciousness, He reveals the eternal relationship with Him and removes all ignorance.
