Augustine of Hippo

"If I have remembered You upon my bed, in the dawnings I did meditate on you [Psalm 63:6]." His "bed" he calls his rest. When any one is at rest, let him be mindful of God; when any one is at rest, let him not by rest be dissolved, and forget God: if mindful he is of God when he is at rest, in his actions on God he does meditate. For the dawn he has called actions, because every man at dawn begins to do something. What therefore has he said? If therefore I was not mindful on my bed, in the dawn also I did not meditate on You. Can he that thinks not of God when he is at leisure, in his actions think of God? But he that is mindful of Him when he is at rest, on the Same does meditate when he is doing, lest in action he should come short.
