Most philosophies teach that we are relatively powerless, that real power exists outside of ourselves in the form of a god separate from his creation. Gods and Goddesses act at their own whim. Then there are fate, past events, genes from our ancestors, society (meaning other people). And it appears that we are under the control of Government, parents, a spiritual hierarchy of ascended masters, forces of evil, and Nature, any thing but inside ourselves.
But the Magical Shaman philosophy teaches that "all" the power that creates your experience comes from your own body, mind and spirit. By just observing an event we change things. If there are no limits, then all the Universe or Source of Life is infinite, and if it is infinite, then all of it's power is at every point of it. This would include the point which you define as you.
Nothing ever happens to you without your participation. Every event that you experience you creatively attract it through your beliefs, desires, fears and expectations, and then react to it from habit or respond to it consciously.
No one really makes us unhappy. You may make yourself unhappy because others don't act the way you want them to or the way you think they should. If you are the victim of some kind of injury or abuse, it is important to realize that something inside of you helped to bring this about.
This does not mean that you are to blame, because you were probably not consciously aware of the beliefs, attitudes, and expectations on your part that were involved.
Also it does not mean the other person was innocent, because what ever they did came from their own beliefs, attitudes and expectations. And to what ever degree they made conscious choices to do harm they are subject to the laws of society.
Never the less, it is important to realize your part in the event so that you can change the factors in yourself that helped bring it about. If the power and magic are in you to create it; then the power is in you to change it.
