Q. Describe about Collective or Universal consciousness?

Neurochemicals and associated brain processes are simply channel selectors for various states of consciousness. All states of consciousness exist independent of the physical body. This relay station works in both directions, that is spiritual, mental, or emotional states trigger neuro electrochemical events in the brain (physical consciousness) and neurochemical stimulation, for example through drugs etc., open access to specific states of emotion, thought, or spiritual awareness. Contemporary physics has proven very clearly that solid physical matter is an illusion and that all is energy only. Therefore, to say that the solid physical brain is the mind, is a mistake. While the brain appears to be solid, it is not. Actually it is the energy appearing solid, but is not solid. It is energy, only. The mind is also energy, an energy that interacts with the energy that creates the appearance of a brain.
