coreSelf Realization
Under the present circumstances, the coreSelf may be realized as a radiance, as just high energy radiating from a central position but with no defined central point, only as an intense energy which is radiates outwards from itself.
The assumption is that it is a radiation force which is spherical but which has no set edge but with a diminishing limit, such that it is limited as it radiates from its center. The radiation is felt as energy flowing away from itself in every direction but being captured and used by the senses, which seek information from any objects those senses detect.
This is such that when a specific sense does not detect an object, or when such a sense cannot detect an object, the core interprets that there is no object to be detected.
The question about the form of this radiance factor, this coreSelf, this atma, presents itself repeated. There were many ascetics and psychologists who took to the task of defining the shape of the self.
At present using a human form, the shape or form of that self cannot be determined with accuracy by the core. However, that does not mean that someone should shout that it is formless.
Probably, the best declaration is that it is indistinct. Its form cannot be determined by it. It is not positioned existentially where it can measure itself. From the inside of itself, it can sense the rays of itself which protrude outwards from its central power. but as to how far away from its core, it can radiate, that it cannot determine. In relation to where its power extends, that too it cannot accurately determine.
Consider one single ray of light which strikes out into space from the filament of a bulb. Can that ray, from its origin-point, measure from within the light, how far it extends? It may determine that it extends about four feet with bright intensity. Then its ray begins to fade for another four feet. Then again, it fades noticeably. But still for the most part, it would be guessing. Why? Because it has no way of accurately measuring that. However, it is not sensible for it to claim exactness about these estimations. They are reasonable amounts but they are approximations only.
