The soul energy theory is that each being with a soul has it's own evolving energy system, and that energies can be combined to form new energies. Crystals also have souls, which means earth is one giant being with a soul, with it's own energy system made even more diverse by it's multitude of life, each with their own energy systems. Crystals, plants, animals and humans all contribute to this, as well as alien life and energies being involved, the earths energy system is constantly changing and evolving with new energies and sometimes old energies being re-awakened.
