Defined in the American Heritage Dictionary as a module consisting of a radio receiver and transmitter (TRANSMITTER + RECEIVER). I have expanded upon this definition to include any person, place, object, or subject that can receive and transmit.
THE TRANSCEIVER IS THE MATRIX that molds and sculpts the input of life-force particles and transforms them to output products or outcomes that can be exchanged for something of equivalent value. (The Paradigm Matrix Book, ChapterThree)
