Seemingly, there exist three spacial dimensions (x, y, z); (width, height, depth).
The second dimension has no third spacial dimension and is depthless (non-existent).
Likewise, the first dimension has no spacial quality and is wholely depthless.
The first and second dimensions are conceptual qualities which exist only to maintain a third dimension.
The third dimension is seemingly the first materially existing dimension.
What does existence exist within?
That which does not exist: does not exist.
That which exists: exists.
Does existence exist within non-existence?
Non-existence does -not- exist.
Through self reflection and material observation, it is discovered that within and without are both micro and macro -eternal-.
This is never-beginning and never-ending: seemingly the quality of a first dimension; of one dimension.
Materialism is seemingly very physical, depthed and 3-dimensional only to the senses. but is empty both reflectively and scientifically.
Senses are a perception of eternal spirit self.
The first, third and fourth dimensions are eternal self.
Self is an english term but the essence of "self" is much deeper than just a "word".
