English term (edited): god Αsiras

Ως «θεός των νεκρών» αναφέρεται ο Όσιρις:

Δεν είναι όμως μόνο η ταυρόμορφη παρουσία του και η ιδιότητα του που σχετίζονται με το δικό μας κείμενο. Ο Όσιρις δολοφονήθηκε από τον αδερφό του Σεθ και η Ίσιδα –αδερφή και γυναίκα του- κατά μια εκδοχή περιμάζεψε και έθαψε τα κατασπαραγμένα μέλη του, κατά μια άλλη εκδοχή τα συναρμολόγησε και επανέφερε τον Όσιρη στη ζωή9, έχουμε έτσι αναγέννηση του θεού, όπως έχουμε αναδημιουργία του μελισσιού. Έτσι ο Όσιρις θεωρούνταν ο θεός των νεκρών, αλλά και η πηγή της ανανεωμένης ζωής αντίστοιχα.

Osiris (Greek language, also Usiris; the Egyptian language name is variously transliterated Asar, Aser, Ausar, Wesir, or Ausare) is the Egyptian God of the Death and the underworld. At the height of the ancient Nile civilization, Osiris was regarded as the primary deity of a henotheism. Osiris was not only the merciful judge of the dead in the afterlife, but also the underworld agency that granted all life, including sprouting vegetation and the fertile flooding of the Nile River. Beginning at about 2000 B.C. all men, not just dead pharaohs, were believed to be associated with Osiris at death.

The origin of Osiris' name is a mystery, which forms an obstacle to knowing the pronunciation of its hieroglyphic form. The majority of current thinking is that the Egyptian name is pronounced aser where the a is the letter ayin (i.e. a short 'a' pronounced from the back of the throat as if swallowing).

Early mythology
God of the dead

Egyptian Museum, CairoOsiris is first mentioned in the 4th Dynasty, though it is regarded as highly plausible that he may have evolved from the god Andjety. In the first mentions of Osiris, he was regarded the god of the underworld and the dead in the Ennead version of Egyptian mythology, in which he was one of the four children of the earth (Geb) and the sky (Nut), and was the husband of Isis (Aset), who represented life. Every Khu, an aspect of the soul, seeking admission to Aaru, the Egyptian paradise, was referred to as an Osiris. As god of the dead, Babi, the god who devoured unworthy souls, was described as his first-born son.

Eδώ η λέξη asiras αναφέρεται σε ακέφαλα όντα χωρίς να αναφέρεται ότι θεωρούνται θεότητες του κάτω κόσμου ή των νεκρών.
Asiras (Sanskrit) [from a not + siras head] Headless; in the plural, headless beings. With particular reference to elementals not possessing what humans would call a head. Used also of the first two human races (TG 35), which means 1) that their mental powers had not yet come into function or been evolved forth, and 2) that in the first root-race, and largely in the second root-race, the then nascent human protoplasts had still a rather vague and globular form which caused Blavatsky to refer to them as pudding-bags.

Osiris (Greek) As-ar, Us-ar (Egyptian) The most famous deity of the Egyptian pantheon, corresponding to Zagreus-Bacchus of the Eleusinian Mysteries. In Plutarch's On Isis and Osiris, Osiris is represented as the son of Nut, space and primordial matter (equivalent to the Greek Rhea) by Seb, celestial fire (Kronos). He became king of Egypt, teaching the people the worship of the gods, and husbandry, and formulating laws. His brother Set, filled with envy, brought about his destruction. Isis, his distraught wife, set out in search of the body, and finally recovered it. But Set then dismembered the body into fourteen pieces, scattering them over Egypt, of which Isis recovered all but one.

After meeting with death on earth Osiris became resurrected, and then became the ruler of the other world (Khenti-Amentet). His death and resurrection depict the drama of the initiation chamber which is one interpretation of glorification or osirification of the defunct human, as mystically portrayed in the Book of the Dead.

Cosmologically, Osiris is the Third Logos, containing in himself the seeds of all things and beings in the universe to be unrolled from the Logos:

"the self-existent and self-creative god, the first manifesting deity (our third Logos), identical with Ahura Mazda and other 'First Causes.' For as Ahura Mazda is one with, or the synthesis of, the Amshaspends, so Osiris, the collective unit, when differentiated and personified, becomes Typhon, his brother, Isis and Nephtys his sisters, Horus his son and his other aspects. . . . The four chief aspects of Osiris were -- Osiris-Phtah (Light), the spiritual aspect; Osiris-Horus (Mind), the intellectual manasic aspect; Osiris-Lunus, the 'Lunar' or psychic, astral aspect; Osiris-Typhon, Daimonic, or physical, material, therefore passional turbulent aspect. In these four aspects he symbolizes the dual ego -- the divine and the human, the cosmico-spiritual and the terrestrial" (TG 243).
Osiris' place in cosmological mythology is seen to be that of the cosmic creator; thus on a more abstract scale Osiris is equivalent to the svabhavat of Buddhist thought. As in other archaic religions and philosophies, when Osiris is considered as an individual divinity, he becomes the cosmic source from which flow forth in hierarchical series of emanations the gradually descending groups of the hierarchy of Light; and from this aspect he is the chief of all initiates of the right-hand path, who thus trace their spiritual ascendance and origin directly to the Third Logos itself.
