Very often therefore it becomes difficult for an intellectual person, who through life has learned things and understood them by the power of intellect, to attain to the inner life. For these two paths are different: the one goes to the north and the other goes to the south. When a person says, "I have now walked so many miles to the south, shall I therefore reach sooner something that exists in the north?" he must know that he will not reach it sooner, but later, because as many hours as he has walked to the south he must walk back in order to reach the north.
