Percy Bysshe Shelley

We rest; a dream has power to poison sleep. We rise; one wand'ring thought pollutes the day. We feel, conceive, or reason; laugh or weep, Embrace fond woe, or cast our cares away; It is the same: for, be it joy or sorrow, The path of its departure still is free. Man's yesterday may ne'er be like his morrow; Nought may endure but Mutability!

The mind in creation is as a fading coal, which some invisible influence, like an inconstant wind, awakens to transitory brightness; this power arises from within...could this influence be durable in its original purity and force, it is impossible to predict the greatness of the result; but when composition begins, inspiration is already on the decline; and the most glorious poetry that has been communicated to the world is probably a feeble shadow of the original conceptions of the poet.

And on the pedestal these words appear:
 'My name is Ozymandias, king of kings:
 Look on my works, ye Mighty, and despair!' 
Nothing beside remains. Round the decay
 Of that colossal wreck, boundless and bare
 The lone and level sands stretch far away.

I arise from dreams of thee, And a spirit in my feet Has led me- who knows how? To thy chamber-window, Sweet!
