14.And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth…

The Word here means sound and energy in the widest sense of the concept, sound and energy that mean flesh in the whole COSMOS, not only the human or animal flesh as it is usually known, but LIFE itself everywhere in this Multiverse.
