Noetic Prayer Is Incompatible with Concealment of Thoughts

Elder Joseph the Hesychast. "Monastic Wisdom".

Heart prayer is not susceptible to delusion, unless one is passionate and already deluded. With heart prayer, as soon as the nous enters the heart, immediately its darkness is cleared and straightaway it becomes peaceful and calm. It rejoices, is sweetened, rests, and is cleansed. It rejoices and becomes like a small child free from passions. Bodily members which used to tempt him become peaceful and humble, just like the hand, the nose, and the rest of the members of the body.
