Beads may be as large as a world, if we are to believe the XV century Indian poet and mystic Kabir:
"Within the Supreme Brahma, the worlds are being told like beads:
Look upon that rosary with the eyes of wisdom."

Or smaller than the tiniest: couldn't subatomic particles be said to be beads in their own right?

To open in wonder our beady eyes at Reality is not a silly passtime.
