"Abba Doulas, the disciple of Abba Bessarion, said: When we were walking along the sea one day, I was thirsty, so I said to Abba Bessarion, Abba, I am very thirsty. Then the old man prayed, and said to me, Drink from the sea. The water was sweet when I drank it. And I poured it into a flask, so that I would not be thirsty later. Seeing this, the old man asked me, Why are you doing that? I answered, Excuse me, but it's so that I won't be thirsty later on. Then the old man said, God is here, and God is everywhere."
