So, O king, does the present life of man on earth seem to me, in comparison with the time which is unknown to us, as though a sparrow flew swiftly through the hall, coming in by one door and going out by the other, and you, the while, sat at meat with your captains and liegemen, in wintry weather, with a fire burning in your midst and heating the room, the storm raging out of doors and driving snow and rain before it. For the time for which he is within, the bird is sheltered from the storm, but after this short while of calm he flies out again into the cold and is seen no more. Thus the life of man is visible for a moment, but we know not what comes before it or follows after it.
