"Absolutely unselfish love is the strongest power in the world, but few are they who can keep it pure from exaction or jealousy, even if it be for one object alone. Your advancement is due to your success in keeping that flame burning ardently for several objects simultaneously. You have done much to develop strength, but you need still more of it. You must acquire discrimination and alertness, so that you see what is wanted at the right moment, instead of ten minutes afterwards. Before you speak or act, think carefully what the consequences will be."
