1 of Hermes Principles.. 

As above - so below, as below - so above. As within - so without, as without - so within. As in great - so in small, as in small, so in great. For everything there is in this world, there exists an analogy on every plane of BEING. So you can realize the great in the small, and the smallest in the greatest. The way you are yourself determines the way you experience the outside world. Vice versa, the outside world is your mirror. When Du change, everything around you will change.
