The recalling of beautiful things, whether they are your own experiences or the acheivements of others, is a creative act. Simple ideas can be restated by rote; but profound ideas must be recreated by will and imagination.
That's what I love about poetry. The more abstract, the better. The stuff where you're not sure what the poet's talking about. You may have an idea, but you can't be sure. Not a hundred percent. Each word, specifically chosen, could have a million different meanings.
