Physical existence is constituted of matter and energy. Matter appears in form of gas, liquid, solid and controversial plasma. Energy appears as heat, magnetic, chemical etc. Energy represents activity ( not meaningful or consciousness activity but conditional ) where in mechanic is divided on potential (energy of rest) and kinetic (energy of movement).

Both of those forms are corresponding opposites therefore they have ability of interaction and transformation from one form in other. But, changes caused by they interaction always stay in frame of physical quality. In other words, non organic matter never can produce living beings or consciousness what gives life to all living beings.

Energy what is necessary for organism or physical activity of the body is not the same as consciousness. Interaction of water, food, oxygen etc. with body don't make consciousness, but only enable it.

All what exist in physical existence have specific form or appearance except, consciousness. We know that brain is in direct connection with consciousness and that brain is matter. Matter can make activity but only in form of energy. In case of that transformation, matter always disappears.

If is consciousness energy, brain as direct material cause, must disappear. Because that is not the case, brain is more like "apparatus" for transmission of consciousness then entity what directly make consciousness. From that we can conclude that consciousness is not the same as matter and energy, but something different. Also, that consciousness doesn't originate from matter and energy, but that is in interaction with them.

Because interaction of difference in existence performs with law of opposites, law of consciousness should have opposite law of physical, and therefore represent non physical law.

For matter and energy are characteristic form and expansion or spreading in space and time, as well as change and distraction of form and therefore represent appearance of existence. Consciousness is meaningful activity without form what have ability of contraction and synthesis or indestructible existence without time and space, therefore it represents essence of existence.

That assertion about consciousness we can notice analysing human consciousness. Human consciousness have no form, doesn't capture space and is not limited either by time or space. Everything what ever begin in her can "stay" there. Any affair we can again experience no matter when and where it happened.

Although people forget nothing ever disappear from they consciousness. Hypnoses is obviously example of that assertion. Freud genius, between other things, is in that that he noticed law of contraction of consciousness.
