Poetry is not like reasoning, a power to be exerted according to the determination of the will. A man cannot say, 'I will compose poetry.' The greatest poet even cannot say it; for the mind in creation is as a fading coal, which some invisible influence, like an inconstant wind, awakens to transitory brightness...and the conscious portions of our natures are unprophetic either of its approach or its departure.
Percy Bysshe ShelleyTrue love in this differs from gold and clay, that to divide is not to take away. Love is like understanding, that grows bright, gazing on many truths.
Percy Bysshe Shelley
