Mother Earth is of duality, as is the snake that she sent. Our bodies our built like Mother Earth, we already had duality even before they took the apple.

The tree of knowledge is our spine, Adam & Eve is inside of us, male and female, that makes us whole.

The Serpent is the kundalini, as Adam & Eve rise up our spine, they would have to do it harmoniously, as a unit, but since Eve was the one that took the apple (crown chakra) first, it opened negativity in the world.

The Fallen Angels, don't like spirituality, as they are scared that we would start disobeying them. The wiped out the Atlantians, Jesus, American Indians, Mayans, etc.
