Our spiritual journey is deeply reflected by the evolution of the voice and by the ways in which we communicate with others. Our fears, softness, sharp edges, peacefulness, and joy are carried to others by our tone, words or lack of words. As people become more whole and in tune with themselves, they usually speak with greater simplicity, resonating from both heart and head.
It is one of the goals of human beings to develop to the point where life is aligned to God in such a way that we behave like an angel in complete service to heaven.
