The "water of life" is flows of energy. (See Appendix 14).
In many papyruses we see the "flower of life" growing from "the waters of the lake" on which Osiris's throne is placed. This "lake" was fed by the "waters of the heavenly Nile" and served as the source from which the spirits of the blessed and the gods drank. The "heavenly Nile" is what they called our galaxy, the Milky Way, in Ancient Egypt. .
This picture is of especial interest from the point of view of comparative mythology as many Semitic writers believed that the throne of the deity was set up or rested upon "a flow of water or a river". Even in the Book of Revelations in the Bible we find mention of "a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb" (Chapter 22, Verse 1).
But today we are beginning to understand quite clearly that "water of life" or "pure river of water of life proceeding out of the throne of God" conceals the concept of "energy" or "energy flows". In this light it is noteworthy the a similar sign
