The entity is a fragment of God or a part of “all that is” which is indescribable and cannot be understood at the human level of consciousness.
Consciousness comes into realities such as this one, with a number of physical forms within the outer body. This is demonstrated by looking at Russian nesting dolls that we have all seen, as one form fits into another.
The difference between the soul and the empty nesting dolls is the differing dimensional frequencies or energy wavelength.
The “nesting” soul forms are at different frequencies that respond to frequencies of existing dimensions all of which hosts the soul (some might call if an “over-soul.”). The Causal body is held by some to be the originating body or the human form.
