The Sufis in all ages have tried their best to train their consciousness. How did they train it? The first training is analysis, and the second training is synthesis. The analytical striving is to analyze and examine one's own consciousness, in other words one's own conscience; to ask one's conscience, addressing it, "My friend, all my happiness depends on you, and my unhappiness also. If you are pleased, I am happy. Now tell me truly if what I like and what I do not is in accordance with your approval." One should speak to one's conscience as a man going to the priest to make his confession, "Look what I have done. Maybe it is wrong, maybe it is right; but you know it, you have your share of it; its influence on you and your condition is my condition, your realization is my realization. If you are happy, only then can I be happy. Now I want to make you happy; how can I do it?" At once a voice of guidance will come from the conscience, "You should do this, and not that; say this and not that. In this way you should act, and not in that way." And conscience can give you better guidance that any teacher or book. It is a living teacher awakened in oneself, one's own conscience.
