The concept of principle and attribute is encoded into this reality.
Observed in the Fibonacci sequence: 1 1 2 3 5 8 13 ...
1 representing the principle, and the second 1 representing the attribute of the principle.
Water is to ice and stream, as
Light is to illumination, as
The soul is to the body, as
The dielectric field is to magnetism,
Or how it was said in ancient texts, Vidya and avidya. In Hinduism, Vidya signifies knowledge and enlightenment, while Avidya represents ignorance and illusion. Vidya being the principle, and avidya being the attribute of.
Trying to understand the world through attributes rather than the principles is definitionally ignorance.
In much the same way as we think we are our bodies instead of understanding that the body is an attribute of the soul that can only manifest once embedded into this array, so too is the magnetic field only an attribute of that which powers it - the dielectric field.
The reason we think "free energy" isn't possible is because we were all taught a skewed and misunderstood explanation for what these forces are, and how they function.
