“O, dreadful is the check — intense the agony
When the ear begins to hear and the eye begins to see;
When the pulse begins to throb, the brain to think again,
The soul to feel the flesh and the flesh to feel the chain.”

The Prisoner (October 1845)
Context: p>But first a hush of peace, a soundless calm descends;
The struggle of distress and fierce impatience ends
Mute music sooths my breast — unuttered harmony
That I could never dream till earth was lost to me.Then dawns the Invisible; the Unseen its truth reveals;
My outward sense is gone, my inward essence feels —
Its wings are almost free, its home, its harbour found;
Measuring the gulf, it stoops and dares the final bound — O, dreadful is the check — intense the agony
When the ear begins to hear and the eye begins to see;
When the pulse begins to throb, the brain to think again,
The soul to feel the flesh and the flesh to feel the chain.Yet I would lose no sting, would wish no torture less;
The more that anguish racks the earlier it will bless;
And robed in fires of Hell, or bright with heavenly shine
If it but herald Death, the vision is divine —</p
