According to Imam, whenever the subject of the hereafter and that of keeping it in mind comes up, it seems that one should withdraw from the world, abandon and flee from it.
Most of our Sufis and mystics have given currency to this dictum and claimed that the hereafter can be attained by trampling on this world, as this world is a world of matter while the hereafter is a world of meaning, and these two are irreconcilable.
