Consciousness is a state that pervades the universe and is not just limited to the brain. The reality of the universe manifests within itself not just the physical aspects of the atoms, stars and planets but also the non-physical realities of the mind and conscious awareness.
Consciousness is not limited to the brain and nervous system, which are in part a product of the all-pervading universal consciousness.
In Indian philosophy, the state of Turiya or the fourth dimension, helps us realize that we are instruments of the creator. The scientifically proven super-fluid state reflects the state of collective consciousness achieved when one becomes the Spirit.
