God works in mysterious ways. Things may look good outwardly, but there may be evil contained inside. Let no one be deluded by pride that he himself has conceived good ideas or done good deeds. If everything were as it seemed, the Prophet would not have cried out with such illuminated and illuminating perspicacity, Show me things as they are! You make things appear beautiful when in reality they are ugly; You make things appear ugly when in reality they are beautiful. Show us therefore each thing as it is lest we fall into a snare and be ever errant.
RumiWhen something goes wrong, accuse yourself first. Even the wisdom of Plato or Solomon can wobble and go blind
RumiKnow that a word suddenly shot from the tongue is like an arrow shot from the bow. Son, that arrow won't turn back on its way; you must damn the torrent at its source.
Rumi
