40 Rules of Love by Shams-i-Tabrīzī

40 Rules of  Love by Shams-i-Tabrīzī (1185– 1250), Persian Mystic, Wandering, Lover of God

Rule 26

The universe is one being. Everything and everyone is interconnected through an invisible web of stories. Whether we are aware of it or not, we are all in a silent conversation. Do no harm. Practice compassion. And do not gossip behind anyone's back – not even a seemingly innocent remark! The words that come out of our mouths do not vanish but are perpetually stored in infinite space and they will come back to us in due time. One man's pain will hurt us all. One man's joy will make everyone smile.
