“Those who are addicted to the imagination have withdrawn from God’s grace and from the realm of Divine revelation. They have abandoned the heart in which grace is revealed and have surrendered themselves to the imagination, which is devoid of all grace. It is only the heart that receives knowledge about things that are not apprehended by the senses, because God, Who dwells and moves within it, speaks within it and reveals to it the substance of things hoped for.”
(St Nektarios of Aegina, collected quotes by Fr Serfes)
