You can become all fire

Abba Paul went to see Abba Basil and said, "Abba, as far as I can, I say my little office, I fast a little, I read and meditate, I live in peace and as far as I can, I purify my thoughts. What else can I do?"

Then the old man stood up and stretched his hands towards heaven. His fingers became like ten lamps of fire and he responded, "If you will, you can become all fire. You cannot be a monk unless you become like a consuming fire."
