This idea is from T.S Elliot. The only difficulty is that there are no words for what you are feeling. It is like a retreat from physical reality, an entry into a realm where the human being ceased to be and your soul takes over. Poetry becomes an attempt by the individual to become invisible, but with a kind of invisibility which illuminates things from within as well as from without. You shake it and they form a pattern, you shake it again and they form another pattern, though they are the same objects.
Poetry is more a musical notation than a reasoned linguistic structure.
Poetry is the arrangement of sounds and words at random, not a conscious effort. In other words, you dissociate your mind from language and let language by chance and pure randomness rearrange itself in newer and newer patterns. The problem then is that there is no difference between that and pure gibberish. I do not see a great difference between poetry and prose. The same concentration and intensity of expression attributed to poetry can be found, for instance, in those novelists who follow the stream of consciousness, like James Joyce.
