I am content to follow to its source

Every event in action or in thought;

Measure the lot; forgive myself the lot!

When such as I cast out remorse

So great a sweetness flows into the breast

We must laugh and we must sing,

We are blest by everything.

Everything we look upon is blest.

-- W. B. Yeats
