The Spark

Readers of riddles dark,
Solve me the mystery of the Spark!

My good dog died yesternight.
His heart of love through his eyes of light
Had looked out kind his whole life long.
In all his days he had done no wrong.
Like a knight’s was his noble face.
What shall I name the inward grace
That leashed and barred him from all things base?
Selfless trust and courage high--
Dust to dust, but are these to die?
(Hate and lust and greed and lies--
Dust to dust, and are these to rise?)

When ’tis kindled, whither it goes,
Whether it fades, or glows and grows--
Readers of riddles dark,
Solve me the mystery of the Spark!
