Enliven your heart with preaching, kill it by denial, energise it with firm belief, enlighten it with wisdom, humiliate it by recalling death, make it believe in mortality, make it see the misfortunate of this world, make it fear the authority of the time and the severity of some changes during the nights and the days, place before it the events of past people, recall to it what befell those who were before you and walk among their cities and ruins, then see what they did and from what they have gone away and where they have gone and stayed. You will find that they departed from (their) friends and remain in loneliness. Shortly, you too will be like one of them.
