George Santayana - "I would I might forget that I am I" lyrics

I would I might forget that I am I, And break the heavy chain that binds me fast, Whose links about myself my deeds have cast. What in the body's tomb doth buried lie Is boundless; 'tis the spirit of the sky, Lord of the future, guardian of the past, And soon must forth, to know his own at last. In his large life to live, I fain would die. Happy the dumb beast, hungering for food, But calling not his suffering his own; Blessèd the angel, gazing on all good, But knowing not he sits upon a throne; Wretched the mortal, pondering his mood, And doomed to know his aching heart alone,
