And their eyes were opened and they recognized him; and he vanished out of their sight. They said to each other, "Did not our hearts burn within us while he talked to us on the road, while he opened to us the Scriptures?"

Luke 24:31-32

No act of virtue can be great if it is not followed by advantage for others. So, no matter how much time you spend fasting, no matter how much you sleep on a hard floor and eat ashes and sigh continually, if you do no good to others, you do nothing great.

- St. John Chrysostom
