Remember death frequently...
Its adherents are only howling dogs and rapacious beasts snarling at one another. Their strong devour their weak and their old subjugate their young. (They are like) cattle, some confined and others left untended. They have lost their intellects and ventured into what is unknown. They are (like) diseasesd cattle left free to graze in a valley of soft sand, difficult to traverse. They have neither a shepherd to keep them in order nor a herdsman to take them to pasture.
The world has taken them them on the path of blindness, and taken their sights from the beacon of guidance, so they are wandering in its perplexities and drowned in its pleasures. They have taken it (the world) as a lord, so it plays with them and they play with it and they have forgotten what is beyond it. Gradually the darkness will become dawn, and it is as if the caravan has arrived; soon those who hasten will meet (the caravan)”.
