Mysticism and magic

Andrei Tarkovsky's Stalker

This complicated question about a parity of these concepts is actual now more than ever. In our time all can be using up everything. Why do some people always seem to take advantage of spiritual things?
In the west as in the east, people always tend to practical advantage. How it can be condemned? It is a private affair of everyone what interests it puts on the first place. But a problem in that that as a result the principles of mysticism and magic - it is constantly confused. I will not consider now a case when practical application of religion consider as magic. It's a big separate theme. And I will not tell about a tantra concept now which was confused strongly enough in west.
No, I speak about principles.
Mysticism and magic are not only different, but frequent opposed.
Mysticism is a spiritual force while magic is a natural force.
Mysticism is freedom, magic is power.
Mysticism is communion with God, magic is communion with cosmic forces generating power. Magic was the first technical means at man's disposal in his struggle against inimical forces, against spirits and demons but it is not pleasant to me when it turns out that it was a source of power over other people or even the higher forces.  
Occultism is related to magic. Magical elements find their way into spiritual life, although magic is never spiritual. Mysticism is, however, always spiritual. Its distinguishing quality is freedom of spirit - a quality denied to magic, which remains, indeed, the servant of maya's duality.
