On the walls of the great Temple of Isis at the Island of Philae there are inscriptions describing the King´s ritual procession through the temple.
The purpose of this wandering, which was performed when a new King ascended the throne was to symbolically enact the Eternal Journey from birth through life to death and resurrection.
These hymns celebrate the cosmic circle; the rise and fall of the Nile, the journey of the sun across the heaven and through the Underworld.
When the King proceeds through the temple the cosmic circles are repeated on earth. Without this celebration Life would not be maintained. Everything in existence is returning back to the source from where it came, back to she who gives birth to the God, to Aset, the Giver of Life, Lady of Philae
