"Abba Lot went to see Abba Joseph and said: Abba, as much as I am able I practice a small rule, a little fasting, some prayer and meditation, and remain quiet, and as much as possible I keep my thoughts clean. What else should I do? Then the old man stood up and stretched out his hands toward heaven, and his fingers became like ten torches of flame. And he said: If you wish, you can become all flame."
