“Then they were silent: words are little aid
To Love, whose deepest vows are ever made
By the heart's beat alone. Oh, silence is
Love's own peculiar eloquence of bliss!”

In Defense of the Earth (1956), She Is Away
Context: Now I know surely and forever,
However much I have blotted our
Waking love, its memory is still
there. And I know the web, the net,
The blind and crippled bird. For then, for
One brief instant it was not blind, nor
Trapped, not crippled. For one heart beat the
Heart was free and moved itself. O love,
I who am lost and damned with words,
Whose words are a business and an art,
I have no words. These words, this poem, this
Is all confusion and ignorance.
But I know that coached by your sweet heart,
My heart beat one free beat and sent
Through all my flesh the blood of truth.
