Childhood. 
When fairies are real and all you need to find joy and magic and belief is a silver penny. 

Grace for Light.

My soul goes clad in gorgeous things,

Scarlet and gold and blue,

And a here shoulder sudden wings

Like long flames flicker through.

And she is swallow-fleet, and free

From mortal bonds and bars.

She laughs, because Eternity

Blossoms for her with stars!
