When we stay restricted to the polarity of the third dimension,  human beings experience the world through the cerebral intelligence of the ego consciousness.  The dualistic cerebral intelligence is the consciousness of our lower mind which functions at the third dimensional level through perpetual comparison, contrast, and separation.

Our whole being of the true self in Divine unity lives from a multidimensional consciousness, and only uses the dualistic cerebral consciousness for practical actions within the third dimension.  The heart consciousness emanates from the center of being.  The heart opens at 4D and 5D frequencies, and utilizes the higher mind in a direct apprehension of knowledge, wisdom, love, and harmony.

The consciousness of the heart is a unitary consciousness.  Our awakening to heart consciousness restores our conscious awareness of the human true self as a multidimensional being.
