It seems to me that the life of man on earth is like the swift flight of a single sparrow through the banqueting hall where you are sitting at dinner on a winter’s day with your captains and counsellors. In the midst there is a comforting fire to warm the hall. Outside, the storms of winter rain and snow are raging. This sparrow flies swiftly in through one window of the hall and out through another. While he is inside, the bird is safe from the winter storms, but after a few moments of comfort, he vanishes from sight into the wintry world from which he came. So man appears on earth for a little while – but of what went before this life, or what follows, we know nothing.
