Work on your stony qualities and become resplendent like the ruby. Practice self-denial and accept difficulty. Always see infinite life in letting the self die. Your stoniness will decrease; your ruby nature will grow. The signs of self-existence will leave your body, and ecstasy will take you over.
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
