The Whole Cosmos is an Ocean of Consciousness. All that exist both animate as well as inanimate form part of this ocean.
Each one of us are travellers in this ocean and are subject to its impact and influence completely.
The human brain is the tool which facilitates in realizing this fact. The brain needs to be trained and tuned to "See" the reality as " It Is".
One becomes a "Witness" to "Oneself" when the brain is "Tuned" appropriately. This "Tuning " is done by a Master who Is in sync with the absolute reality of the Ocean of Cosmic Consciousness.
