“ As long as we lean on anything outside ourselves for support, we are going to be insecure. Most of us try to find support by leaning on all sorts of things - gold, books, learning, sensory stimulation - and if these things are taken away, we fall over. To the extent that we are dependent on these external supports, we grow weaker and more liable to upsets and misfortune. ”
