Intents and Purposes: Shamanic Practice.
The act of energy consumption, either natural or forceful is shamanism.
Shamanism is the act of manipulation of energies and elemental states for divine intent and purpose.
Shamanism is also hence Elementalism.
Elementalism is the act of manipulation of elemental energy, and the elements themselves, as we are elemental hence why we also feed on elemental energy. Elemental energy can be seen and felt.
When you see rivers, rain, storms, the sun, the moon, desert air, you are experiencing elements, and when you feel their energy you are feeling elemental forces and energy.
