I never really liked the term "Higher Self". It adds even more confusion and complexity to the question "Who am I?". And the answer is stupidly simple - I am me, of course!
Maybe the confusion about who or what we are stems from an effort to locate ourselves in space - we know we are the being located "here", and here is this body, so we are the body or, at least, "inside" the body. Hmm.... Space is a tricky concept. We usually try to understand time and we get all kinds of sophisticated theories about it, but we take space for granted. Because it is so obvious.
The easiest way to get our mind out of it's usual operating mode is to parallel life to a computer game. This way we can have an exterior viewpoint of life, space, time and our own existence. When we play a computer game, we can identify ourselves with a character in the game, but at any given time we know we are not that identity. We see with our own eyes, not with the character's eyes. We make him move being exterior to him, not inside of his body.
But let's think of an advanced virtual reality equipment that would allow us to view the game through the eyes of a game's characters - and make his body move as if we occupied it. What would have happened?
Would we have changed space? No.
Would the origin point of our awareness - our point of existence - have moved? No.
We would have simply changed our viewpoint. Nothing would have changed with us.
But if a vicious scientist managed to get us trapped in this virtual reality, we would sooner or later believe that WE ARE the character in the game - you see, we tend to locate ourselves at the point we view from.
And yet, the character in the game would be nothing more than a digital image. Much like our physical body...
The example above clarifies that such "location" is nothing more than an idea of position in relation to our surroundings. It is not us - or our awareness point - that move or change.
All space is virtual. It only exists because of the various parts it supposedly contains - atoms and molecules or bits and bytes, depending on which universe we are talking about.
Trapped this way in the virtual reality, having lost our original viewpoint, we might never find out the truth.
Or we might consider the existence of a "Higher Self" - the guy outside the monitor. But we wouldn't be inside the monitor either. We would simply think so. And in our present condition, we simply think so.
