Doubt is a precipice on the way to God. Blessed is he who is freed from its bonds. He who fares without any doubt, adhere to his footprints if you do not know the way. Cleave to the footprints of the deer and advance with care that you may reach the musk-gland. By means of such trekking, even if you walk on fire, you will reach the luminous peak.
RumiSorrow prepares you for joy. It violently sweeps everything out of your house, so that new joy can find space to enter. It shakes the yellow leaves from the bough of your heart, so that fresh, green leaves can grow in their place. It pulls up the rotten roots, so that new roots hidden beneath have room to grow. Whatever sorrow shakes from your heart, far better things will take their place.
Rumi
