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 gulph, it stoops and dares the final bound,

"Oh I 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.

Emily Brontë
