"And grant us, O Lord, when we go to sleep, repose of body and soul; and keep us from the murky slumbering of sin .... And grant us, O God, a watchful mind, a chaste thought, a sober heart, and sleep light and free from all satanic phantasies."
Monk Antiochus
one of the Prayers "After the Supper Service"
quoted by Constantine Cavarnos in
The Priest as Spiritual Father
