Since using the Higher Self mandala I have experienced its effect as integrating the parts of myself or doing the opposite of what is known as dissociation.
But I have always had the idea that the Higher Self was something that existed beyond the parts of the psyche; beyond the id, ego, and superego.
So I searched for an article that would address how the Higher Self correlates to the psyche.
I found this:
"The transpersonal: transcending the Ego
While your “outer self” - the daily waking consciousness of the Ego - is focused upon the external world, your inner being encompasses all aspects of your consciousness. Your inner being includes your outer self, your subconscious mind, the “unconscious” parts of mind-body functioning, as well as the super-consciousness of the transpersonal realm. Your inner being is your complete consciousness. It is all of the “separate” parts of your consciousness in one unified package. Your inner being is also the real you, the complete you. It is also been referred to as your “Higher Self.” In a state of mindfulness, it may act as witness to the workings of the mind and the Ego."
That matches up well with my experiences from using the mandala. It is saying that the Higher Self is not so much reached by leaving the ego behind as it is by bringing all the parts of yourself, ego included, into a healthy working relationship with each other. That would be the opposite of dissociation.
Most of what I have read about the Higher Self put it in terms of leaving the ego behind. But there is a missing link between these two ways of looking at what the Higher Self is.
Prometheus Rising by Robert Anton Wilson
He believes that one stage of human development is reached after all the parts in the current stage are brought into balance with one another. With that in mind I could see how the Higher Self could be both the state we reach when we integrate the parts of ourselves and also be the state that becomes available to us which is beyond the parts of ourselves.
