Elder Joseph the Hesychast. "Monastic wisdom". Letter 36.
May the God and Lord of all Who dwells in the heavens, Who gives us breath and life and everything, and constantly cares for our salvation, send forth into your holy souls the comforting Spirit; may He enlighten your nous as He enlightened the Disciples of our Savior; may He shine the light of His divine radiance upon your entire spiritual and noetic being; may your whole heart burn with divine eros as did Cleopas’s, and may it leap for joy learning of the conception of the new Adam, and the utter destruction of the old Adam along with all his passions. Then, in this manner, tears will continuously flow every moment like a fountain streaming forth sweetness. Amen.
Today, my little child, I received your letter and saw what you wrote, and I shall answer your questions. The method of noetic prayer is as your holy eldress tells you. Circular* prayer within the heart has no danger of delusion ever. The other method or methods are dangerous, because a fantasy can easily approach them, and then delusion enters the nous.
O how dreadful is the delusion of the nous! And how imperceptible! Let me write a little about it for your information. I was very daring with these things and examined every kind of prayer. I tried out everything, because when grace approaches a person, his nous—that “shameless bird” as Abba Isaac calls it—seeks to penetrate everywhere, to try out everything. It begins with the creation of Adam and ends up plunging into depths and soaring to such heights that if God did not set any boundaries, it would not return.
