UNITARY CONSCIOUSNESS

Unitary consciousness occurs when there ceases to be subject-object awareness.  "I" see "it," subject, predicate, object.  For us humans, it is the usual state of mind.  Unitary consciousness is the opposite of subject-object awareness.  In unitary consciousness, all is "one."

Vedanta terms this the untying of the three knots of knowledge:  the knower, the knowing, and the known.  The resultant "one" is Brahman.
