Osiris: Egyptian Usi... Lord of Eternity... God of Death and Resurrection... The First King of Egypt... The Sixth Member of the Ennead of Heliopolis
Slain by his brother Set and revived by his wife Isis... again slain and passed to the Land of the Dead wherein he becomes Lord of the Otherworld. The Egyptians all hoped to share in the resurrection of Osiris.
Also an Agricultural God, his first death is the planting of seed and his second the harvesting and grinding of the ripe grain.
The Hermetic Order of the Golden Dawn gleaned much through Egyptian symbolism. Osiris is highly recognized within the rituals of the Outer Order and the transition between the Outer and Inner (Portal Grade). Gathering of Osiris... body parts by Isis is linked to the gathering of the symbols of the elements on the altar. Within the Outer Order Rituals, the Hierophant takes on the visual form of Osiris. A similitude with that of Christ is obvious.
"For Osiris on-Nophris who is found perfect before the Gods, hath said: 'These are the Elements of my Body, Perfected through Suffering, Glorified through Trial. For the scent of the Dying rose is as the repressed Sigh of my suffering: And the flame-red Fire as the Energy of mine Undaunted Will: And the Cup of Wine is the pouring out of the blood of my Heart: Sacrificed unto Regeneration, unto the Newer Life: and the bread and Salt are as the Foundations of my Body, Which I destroy in order that they may be renewed. For I am Osiris Triumphant, even Osiris on-Nophris, the Justified: I am He who is clothed with the body of Flesh, Yet in whom is the Spirit of the Great Gods: I am The Lord of Life, triumphant over Death. He who partaketh with me shall arise with me: I am the Manifestor in Matter of Those Whose Abode is the Invisible: I am purified: I stand upon the Universe: I am its Reconciler with the Eternal Gods: I am the Perfector of Matter: And without me, the Universe is not.'" (Golden Dawn, Vol. III, Book 5, Enterer of the Threshold)
