eliphas levi's three fundamental principles of magic:
1. the material universe is only a small part of total reality, which includes many other planes and modes of consciousness. full knowledge and full power in the universe are only attainable through awareness of these other aspects of reality. one of the most important of these levels or aspects of reality is the "astral light", a cosmic fluid which may be molded by will into physical forms.
2. human willpower is a real force, capable of achieving absolutely anything, from the mundane to the miraculous.
3. the human being is a microcosm, a miniature of the macrocosmic universe, and the two are fundamentally linked. causes set in motion on one level may equally have effects on another.
