The Communication Gap - Glen C Cutlip - Bog

Breaking the cosmic communication barrier is breaking the constricted barrier of the dual mind. Have you ever wondered why there are those who have ears that hear not and eyes that see not? It is evident that it’s not enough to simply hear or see things, for there is something missing when one simply does that.
By breaking the barrier of the dual mind, we come to see and not see at the same time, and to hear and not hear at the same time. We come to have ears that hear and eyes that see. This is why the deaf are said to hear and the blind are said to see.
