The soul is not the “devil” on the other shoulder. 😉 It is much, much more that that. It is the energetic essence of who you are when you are here in life on the planet, and it also continues after you die. This is my belief. I also believe that it is not inside of us, but we, as biological beings, are inside of it; it’s bigger than we are and extends into what folks call a person’s “aura.” It doesn’t really have a moral compass as such, for outside of life here on Earth among other humans, there is no right or wrong; these concepts are relative (sorry, they are) to how we choose to interpret our human biological experience.
Love and expansion of the soul into the world are its goals. All experience is its nourishment. It is both the Fool and the World in my Tarot cards, the beginning step into the world, and the union of all matter and energy at the end of the universe of time and space.
So, keep in mind that the soul’s desire for experience will often try to trump your ideas of right and wrong. It will be up to you to discern which to follow in any given moment, for free will trumps everything. 🙂
