As though a rose should shut and be a bud again. - John Keats

But strength alone though of the Muses born
Is like a fallen angel: trees uptorn,
Darkness, and worms, and shrouds, and sepulchres
Delight it; for it feeds upon the burrs,
And thorns of life; forgetting the great end
Of poesy, that it should be a friend
To sooth the cares, and lift the thoughts of man.

No, no, go not to Lethe, neither twist
Wolfs-bane, tight-rooted, for its poisonous wine;
Nor suffer thy pale forehead to be kiss'd
By nightshade.

The excellency of every art is its intensity, capable of making all disagreeable evaporate.
