"The true believer is one who always occupies himself with mention (dhikr) of the Lord (Khudawand), whose heart is full of love and whose tongue is busy with glorification of the Creator (Khudawandgar). He will hear the instructions given to those who tread the path of truth, will act accordingly, and will admonish his friends, thus acting righteously himself first, and later on inducing others to do so.
 
Man attains the recognition of his Creator when he acquires knowledge of himself. First you must acquire the knowledge of your body, limb by limb. You should realize that it has not come into existence by itself, but has been created by some one else. Then you should reflect: who is this who has created me? For what purpose? Where is he going to take me? — Then you will see that if your body maintains a state of balance in its elements, it will be free from disease. Otherwise its condition will be upset. He must then abstain from unsuitable foods. He may thus infer that if one abstains from excesses, in every thing observes a proper measure, not deviating from it to either side, and if he purifies his moral self, whenever he discovers in himself the properties of brutes and beasts, he then acquires human properties, and purifies himself. And when his heart has become pure, and doubt and dishonesty leave his mind, when, he acquires certainty in the recognition of the Imam of his time, seeing him as everywhere present before him, looking upon him, he then reaches the stage of self evident certainty ('ilmu'l-yakin), and attains the stage of absolute truth (haqqu'l-yaqin) when his heart becomes enlightened by the absolute light and in that light he begins to see his soul (jan). Thereafter he begins to see with absolute self-evidence the place in which his Creator is."
