—Know, that this world is one stage of our life for eternity. For those who are journeying in the right way, it is the road of religion. It is a market opened in the wilderness, where those who are travelling on their way to God, may collect and prepare provisions for their journey, and depart thence to God, without sorrow or despondency. —The world is delusive, enchanting and treacherous. —The world will be brought to the great assembly at the last day, in the form of a woman with livid eyes, pendent lips, and deformed shape, and all the people will look upon her, and will exclaim, “what deformed and horrible person is that, whose aspect alone is severe torture to the soul.” And they will be answered, “It was on her account that you were envying and hating one another, and were ready to slay one another. It was on her account that you rebelled against God, and debased yourselves to every sort of corruption.” And then God will order her to be driven off to hell with her followers and her lovers.[60] The Lord Jesus (upon whom be peace!) declares that the world is like the man who drinks sea water. The more he drinks, the more his internal heat increases, and unless he stops, he will destroy himself by drinking. CHAP. IV. On the knowledge of the future world. —Know, beloved, that we cannot understand the future world, until we know what death is: and we cannot know what death is, until we know what life is: nor can we understand what life is, until we know what spirit is. —The following is an illustration of the duration of eternity, so far as the human mind can comprehend it. If the space between the empyreal heaven to the regions below the earth, embracing the whole universe, should be filled up with grains of mustard seed, and if a crow should make use of them as food and come but once in a thousand years and take but a single grain away, so that with the lapse of time there should not remain a single grain, still at the end of that time not the amount of a grain of mustard seed would have been diminished from the duration of eternity.— AL GAZZALI ON PRAYER.
