I still don't understand why you're so fixed on attaining ultimate knowledge if it doesn't grant you anything. You seem to recognize that science grants far more utility, application, and overall anything compared to mysticism. So far, the only thing you said mysticism grants is the usual cliches, such as compassion and some other noble sounding stuff. From there, you were quick to point out the lack of compassion in the world which I would attribute to many other things before I'd attribute it to lack of mysticism. Mysticism isn't needed in order to have compassion and I'm not even sure it's the best way to get it.
The pursuit of this ultimate knowledge, the way you see it, all seems pointless in the end. You attain it, and then where do you go from there?
