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.
RumiOne day you will take me completely out of myself, I'll do what the angels cannot do. Your eyelash will write on my cheek the poem that hasn't been thought of.
RumiWhen you resolve to become pious, the devil in your nature cries out at you, "Tread not those paths, O confused one; distress and poverty will overcome you. You will be despised, let down by friends, you will regret it." Dread of the devil has bound their souls; the cries of the devil are the drover of the damned; the call of the Lord is a guardian of the saints.
Rumi
