the Teaching of the Sufis

The majority of religions live, act, believe in accordance with holy scriptures, precepts and commandments. At the same time there has existed a teaching of learned followers who have tried to put into practice all religions, all sayings, all teachings without infatuation, without faith. They did not worship blindly. Before accepting something they practiced it. What could be put into practice was accepted, what could not be was rejected. In this way a new religion was formed, although the material for it was taken from other religions.
The teaching about which I speak now is the teaching of the Sufis.

This teaching says the following about the angel and the devil: every action of a man, every step, every moment, every movement emanates either from the one or from the other. Emanations from both (result) are equally deposited in the human organism in the form of certain crusts of real tangible matter which one can examine and distinguish whether the crust is of one kind or another. Each crust obeys certain laws, leads to certain consequences. And in the case of man things whispered by the devil have a greater effect.
