Jalaluddin Rumi said this quote

Your depression is connected to your insolenceand refusal to praise. Whoever feels himself walking on the path, and refuses to praise--that man or womansteals from others every day--is a shoplifter!The sun became full of light when it got hold of itself.Angels only began shining when they achieved discipline.The sun goes out whenever the cloud of not-praising comes.The moment the foolish angel felt insolent, he heard the door close.
