Conventional: The exchange of information between minds through a system of outer symbols such as words. ACIM: The direct joining of minds, through the extension of one mind to another. "Communication ends separation" T-8.VII.4:1. Conventional communication is actually pseudo-communication designed to disrupt communication. 1. In Heaven, communication is the direct, unmediated and non-specific sharing of knowledge between all minds. It is also the means by which creation occurs (see extension). 2. The separation was a disruption in communication. This is the ego's sole purpose for all that it does. The ego invented bodies and human language in order to not communicate while appearing to communicate. 3. The Holy Spirit is "the remaining communication link between God and His separated Sons" (C-6.3:1). There is no communication at all between the ego and the Holy Spirit. 4. The Holy Spirit guides us to re-establish communication with our brothers through letting go the blocks to joining (see forgiveness) and so experiencing our oneness. 5. The Holy Spirit sees the body solely as an instrument of communication. It is a temporary communication device, needed because our vision is still dim (see M-12.3:3-8). It becomes unnecessary when our minds learn that they can communicate directly without it (see T-15.IX.7:2). 6. The holy instant is a time in which we give and receive communication. 7. Revelation is direct communication from God, which we can experience in this world. See communion. See T-4.VII.3-4, T-15.IV.8, T-15.XI.7, T-18.VI.83-8.
