i saw a bumper sticker i really liked "The more you know, the less you need."
if you accept ideas as possessions, then learning new things can reveal all kinds of infinity. Its this feeling of abundance that satisfies the need for possessing.
i thought about this just now because the cafe is playing Amazing Grace, and there is a line in there about the abundance of time. "We've no less days to sing God's praise than when we first begun." I happen to find it useful to believe that my consciousness will exist forever, and I find joy in a reminder that a) time is infinite, and b) all things change with time. So take a deep breath, and relax. While you're at it, read greatday.com.
