Because I've been listening to so much Beethoven recently, I re-read RAW's "Beethoven as Information" essay in The Illuminati Papers. All of it is valuable; here is one paragraph I particularly like:
"Perhaps some mystics have achieved higher levels of consciousness than Beethoven (perhaps!), but if so, we cannot know of it. Aleister Crowley once astonished me by writing that the artist is greater than the mystic, an odd remark from a man who was only a mediocre artist himself (although a great mystic.) Listening to Ludwig, I have come to understand what Crowley meant. The mystic, unless he or he is also an artist, cannot communicate the higher states of awareness achieved by a fully turned-on brain; but a great artist can. Listening to Beethoven, one shares, somewhat, in his expanded perceptions; and the more one listens, the more one shares. Finally, one is able to believe his promise: if one listens to that music enough, one will never again be unhappy."
