The Seven Planes of Existence is a conceptual model to help us understand the Creator of All That Is. Vianna Stibal says, "It is through the Creator of All That Is that we learn how to create physical healing, how to progress spiritually and how to find enlightenment.
The First Plane is all inorganic material - rocks, soil, minerals and crystals.
The Second Plane is all organic material - vitamins, plants, trees and the spirits that protect the earth.
The Third Plane is where animals and humans co-exist.
The Fourth Plane is the realm of the spirit, where humans exist after death.
The Fifth Plane is where both positive and negative entities co-exist. Positive entities can include angels, enlightened beings and Ascended Masters.
The sixth level is the Laws. This includes all the laws that govern the universe, the galaxy, the planets and ourselves.
The Seventh Plane is the Creator of All That Is, the pure energy of creation.
