The vastness and 5 Body complexity of human potential is widely recognized (outside of the mind-dominated modern culture schooling environment).
A key used in Magus Training is that the majority of human potential lies on the far side of a Doorway called the Adult Ego State.
What the Adult Ego State is, and how you get there, is well understood.
Going through the Adult Ego State Doorway and entering the Extraordinary and Archetypal Domains is another matter... It is not complex. It is not even difficult. But it is does require a different way of Being that emerges as a consequence of relocating your Point Of Origin to the archetypal context of Radical Responsibility.
And yet, this is where Magus Training begins: on the other side of the Adult Ego State Doorway.
