It is right it should be so:
Man was made for joy and woe;
And when this we rightly know
Through the world we safely go.
Joy and woe are woven fine,
A clothing for the soul divine.
Under every grief and pine
Runs a joy with silken twine.
The babe is more than swaddling bands,
Throughout all these human lands;
Tools were made and born were hands,
Every farmer understands.
Every tear from every eye
Becomes a babe in eternity;

~William Blake, excerpt from "Auguries of Innocence"
