We can imagine (without creating specific images in mind) how a point without dimensions moves and makes a line. We can say about the latter that is “created” in this way by a movement of a point. Now we have one dimension. In the same way, an amplitude, or a movement of line with the angle perpendicular to self “creates” a plane with two dimensions, and a movement of a plane perpendicular to self “creates” three-dimensional body. If we use the same phrases to continue the same process, we can say that a movement of a body perpendicular to self creates an object inside our universe. But what does now “perpendicular”? In every previous case, it was indicating a direction which do not exist. Thus, a movement of a line creating a plane is executed towards its thickness which do not exist. In each of these three cases – a point, a line and a plane – we add new notion which neither can be concluded nor imagined within its own dimensions. Hence, “perpendicular” actually means “to exit out of this world” and similar movement or rolling is consumed by higher dimension or is represented in it. A line becomes a plane due to movement and we get a reality due to movement in time. To reach a point of view of the next, higher dimension, we must develop special consciousness, where the last added movement is not treated as such anymore, but is perceived with integrity of a new dimension. Since we didn’t master this concept as a whole, time seems to us a such unusual type of dimension. It seems to develop a new base, represents some kind of intended dimension. But in reality, it is the same by character, and our perception of a body – you know the volume thanks to touch, thanks to sense of density, and when we see body we imagine its properties like this. But we are nurtured in the way that we are thinking incorrectly about ourselves as three-dimensional beings, and duration in the fourth dimension never seemed to be necessary for our reality. And now we “have grown” to the need to make a full turn under the right angle and understand that as three-dimensional beings we are real in the same way as a point, a line and a body. The perpendicular of our new dimension is the extension in time, absolutely necessary for real existence of any object in our universe. This direction is not intrinsic to three-dimensional body.
We can mention here one wonderful fact: none of the “things”(I use this term in very literal meaning, understanding physical things) can possess existence if it does not possess the maximum number of dimensions realized by us. It seems to be an axiom that can be applied to the whole created world as we know it, to all beings in our plane of existence. In the first information about geometry we learn that point does not have magnitude. That’s why it doesn’t possess existence, besides imaginary existence, and only when imagination is foggy and revolving around notion without any tries to treat it seriously. A line has length, but does not have width, that’s why it can exist only in imagination – the same way as unlucky point. Further we learn that plane has length and width, but not thickness, and that’s why it impersonates something that can not possess existence. Finally, we’re coming to a body that have length, width and height, that’s why we consider it quite dense for existence as it is imagined from the point of view of good mind. However, it is still able to exist only in undefined imagination of the same type as a line and a plane, because it does not have duration in time. If it does not possess time dimension or does not exist within measured time duration, it can’t be perceived as “thing” in any case. Thus, it can only get existence in our newly found four-dimensional universe. It is the same simple explanation as any other – explanation of necessity of the fourth-dimension – time dimension – to provide substantiality to all objects.
