"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."
