"A brother went to the cell of Abba Arsenius at Scete and, looking through the window, saw the elder as though he were all fire, for the brother was worthy to see [this.] When he knocked, the elder came out and saw the brother looking astounded. “Have you been knocking for long?” he said to him. “You didn’t see anything here?” but he said: “No.” The elder conversed with him and sent him on his way."
