Walt Whitman: Youth, Day, Old Age and Night

Youth, large, lusty, loving—youth full of grace, force, fascination,
Do you know that Old Age may come after you with equal grace,
force, fascination?

Day full-blown and splendid-day of the immense sun, action,
ambition, laughter,
The Night follows close with millions of suns, and sleep and
restoring darkness.
