Everything that is, out of which Energy and Matter manifest and Life evolves. Consciousness is the beginning of all things and part of the trinity of Consciousness, Energy and Matter. “Consciousness just IS!” We can’t really define consciousness because we are nothing but consciousness and consciousness cannot really define itself. “I AM THAT I AM.”
Our personal consciousness includes all states of awareness and our experiences of fear, love, hope, desire, happiness, sadness, depression, ecstasy, mystical union, etc. We experience connectedness through consciousness
Consciousness is not a "thing" nor is it a function of a "thing" called the brain. Killing the brain doesn’t kill consciousness but it limits its expression in the familiar physical world. Consciousness is expressed through the brain, but it exists outside the brain. Consciousness acts upon the physical world, like a “force,” as in telekinesis.
There are three levels of consciousness:
I for Instinct, a function of the lower subconscious
I for Intelligence, a function of the ordinary consciousness
I for Intuition, a function of the super-consciousness
