20. The very same night while I was sleeping Satan attacked me violently, as I will remember as long as I shall be in this body; and there fell on top of me as it were, a huge rock, and not one of my members had any force. But from whence did it come to me, ignorant in the spirit, to call upon Helias'? And meanwhile I saw the sun rising in the sky, and while I was crying out Helias, Helias' with all my might, lo, the brilliance of that sun fell upon me and immediately shook me free of all the weight; and I believe that I was aided by Christ my Lord, and that his Spirit then was crying out for me, and I hope that it will be so in the day of my affliction, just as it says in the Gospel: In that hour', the Lord declares, it is not you who speaks but the Spirit of your Father speaking in you.'
