Now I shall explain to you this idea: a thief is thinking of robbing the person with whom he is travelling. That inclination makes him concerned with his own benefit and indifferent to the benefit and the feeling of the other. That inclination is coming from the spirit which the Sufis have called Nafs. I will give you another amusing example: if there are four or five persons at the table, one of them fixes his eyes on the best cake. It is a very mild inclination, but it comes from nafs.
