The question arises: how can we withhold, how can we keep something from falling into the mouth of Qaza? And the answer is: by controlling our body and our mind. In the East I have seen a man lifting a heavy stone on one finger. One might wonder how that can be possible, but it is the power of will alone which sustains the heavy stone; the finger is only an excuse. I have seen those who experiment in the field of spirit and matter, jumping into the raging fire and coming our safe, cutting the muscles of their body and healing them instantly. It is not a fable that the mystics know how to levitate; it has been seen by thousands of people in India. I do not mean that this power is something which is worth striving for, I only wish to point out what can be accomplished by the power of will.
