Transformation is intensional change. Intention is awareness. Intention maps intension into extension. Dreaming maps extension into intension. Physical Science tells us that all is energy.
Energy is the content side of the equation.
Mass is the form side of the equation. Speed of light motion is the functional quantifier of interchangeability. Neural Science tells us that all sensation originates in electrical energy vibrations. Human perception operates as an orderly system of progressively abstract bindings. Perceptual content and form are measured fixations of neural energy within some individual cognitive system or belief structure, according to universal laws of competetive evolution.
