I was not an atheist at the time. Go figure. Likewise, it took several years to drill down through this multi-layered, multidimensional experience. No doubt I will discover much more over the next several years.
Again, for the dim or slow, understanding is an evolutionary process. The huge mistake is to take such a vision at face value, pun intended. If you ever have to good fortune to have such an encounter you will understand some of what I am trying to convey. The problem is that the image is so dazzling that it is very easy to get sucked into it and miss what is going on behind the scenes. You say this is not unusual. It is the very definition of an unusual experience and is hardly a commonplace occurrence. I'm not suggesting I'm the only one to have been treated to this level of intrigue, but I clearly recognize that is very much out of the ordinary realm of endeavors.
Again, it was this experience that has helped to form the basis or foundation of a definition of personality that is well beyond what we are used to hearing. The idea is that at the core of the individual is the larger identity of the source self. You could also describe this as the entity which is an individualized aspect of consciousness that is by nature, multidimensional, in that it exists in innumerable different realities simultaneously and is aware of itself in each of those realities. In larger terms, the source self, the larger identity is what gave rise to our notions of god. God is the externalized version of our latent and highly distorted ideas or perception of the larger identity. Last, but not least, all aspects of the source self as one with the source self though inherent awareness of this internal feature is rarely conscious to the aspect self. Finally, your larger identity is not my larger identity. The much vaunted Oneness we hear about so often is a ruse and a distortion of the above.
