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.
