The experiences stored within the energies that are associated with the gross and spirituo-physicality of the human body (the seven frequency levels associated with the Chakras and the Human Aura), create a lower grade copy of the identity of the aspect (soul), and ultimately a separately functioning personality called the ego.
The ego is that which most incarnates refer to as the “self” the “I am”.
Once the incarnate aspect starts to think along the lines of the ego being the self, everything else is created in separation from that which the incarnate aspect really is, an energy projection from the True Energetic Self (God Head, Over Soul, Higher Self), the energy that makes us an individualized unit of God, of the Source Entity.
Somewhere during the process of the creation of the ego it becomes self-aware, and, recognizing its own transient position, does everything it can to perpetuate its existence. This includes “hiding” the underlying knowledge of the True Energetic Self, so that the aspect does not become self-aware whilst incarnate and dissolve the ego in the light of self-realization before the demise of the human body.
The ego is dissolved at the point of the demise of the human body, irrespective of its efforts to perpetuate its own existence, which are of course futile.
