"Advice from the Master. I know that your one object in life is to serve the Brotherhood; yet do not forget that there are higher steps before you, and that progress on the Path means sleepless vigilance. You must not only be always ready to serve; you must be ever watching for opportunities—nay, making opportunities to be helpful in small things, in order that when the greater work comes you may not fail to see it."
