Dimensions are nothing but mathematical constructs. Witness that the 2nd dimension ( a surface) is describe by it length and width (L x W). The 3rd dimension (a solid) is defined by it length, width and height (L x W x H) If each unit is the same in these mathematic equations, the dimensions becomes that unit to the exponent of the dimension. 2nd dimension is Y2 (Y x Y). 3rd dimension is Y3 (Y x Y x Y). Naturally the rest of the dimensions are the same: 4th dimension is Y4 (Y x Y x Y) and the 5th dimension is Y5 ( Y x Y x Y x Y x Y) and so on.
Why are we doing this? Why look at this and draw out these mathematical constants? What purpose could it possible have?
We are looking at the process from the 2nd dimension to the 3rd dimension. To understand other dimensions,the process is THE SAME. It may be difficult to comprehend the 4th dimension, 5th dimension or the 26th dimension (according to physicist there are 26 know dimensions). However it is easy to understand the 2nd and 3rd dimension. This gives us insight into other dimensions (worlds, vibratory planes or realms).
The picture above shows the difference between the Square Root of Two and the Square Root of Three...visually! One goes through a square the other goes through a cube. Another way to look at this phenomenon of dimension is to think of your body as 3D but the shadow that is cast or reflected on the ground by light is 2D.
The diagonal of a square which exists in two dimensions is the Square Root of Two. The diagonal of a cube which exists in three dimension is the Square Root of Three. Therefore the diagonal of something that exists in the 4th dimension is the Square Root of Four. But the Square Root of Four is the number 2. Thus we have arrived at why this world has a presence of duality.
The duality of this world is nothing but the reflection from the 4th dimension. To understand the polarity of this world, why it exists and why it must be so, realize that they are reflections from higher sources. Thus is the beginning to understanding our universe and why its important to realize that all that you see or feel is not all that exists. There are higher faculties and forces affecting and effecting our world. To understand them you must understand higher things.
