The third center, the solar plexus, is the center of consciousness to manipulate the material world. It allows you control over your body, it allows your nervous system to be strong enough to handle the energy. And remember the only thing that this universe ever asks you is, have you had enough, do you want more? And when you say uncle, when you get scared or tired, then the universe slacks off and lets you take that pass. But if you are able to keep up, and are strong and push yourself just a little, then you have the chance for growth and to become more than your essence that your born with, the chance to become that infinite being.
