But, we are three-dimensional, are we not? Aren't the table, the chair, the dog and the steak we had for dinner solid objects with length, depth, height and existence in time? What exactly are these objects we perceive as existing solidly in space for varying periods of time? What is the space we define as separating the objects? How are they connected in time? If physics seems to indicate to us that All is One, then what is it - what characteristic do we possess - that separates us from this deeper reality? And, what is the true nature of this reality?
Space, as we perceive it, has only three dimensions; length, width, and height. We define this condition as three independent directions - that is, each measurement lies at right angles to the others simultaneously. But, again, if we take quantum theory seriously, then "our" space is merely an aspect of another space, possibly of infinite number of dimensions.
If space is infinite, then it must possess an infinite number of lines perpendicular and not parallel to one another. Is infinity, then, a foolishness and does space necessarily have a limit? If it does have a limit, in what space does our space exist?
Now, if space does possess an infinite number of lines perpendicular to one another, then we must ask why we can only perceive three. If we exist in a condition of mind that perceives only three dimensions, this can mean that the properties of space are created - or differentiated - by certain attributes within us. For some reason or another, the Whole is inaccessible to us.
