If your knowledge of fire has been turned to certainty by words alone, then seek to be cooked by the fire itself. Don't abide in borrowed certainty. There is no real certainty until you burn; if you wish for this, sit down in the fire.
RumiIt is as if a king had sent you to a country to carry out one special, specific task. You go to the country and you perform a hundred other tasks, but if you have not performed the task you were sent for, it is as if you have done nothing at all. So people have come into the world for particular tasks, and that is our purpose. If we don't perform it, we will have done nothing.
Rumi
