In our Flaming Sword Sepher Sephiroth, the main entry for Nephthys, “Lady of the Temple” (neb-hwt), can be found under the number 71 (NBTI). Her name is derived from the ancient Egyptian root neb, meaning “mistress”, and hwt, “temple enclosure”. Thus she is the Lady of the House and the archetypal temple priestess. She is the principle (neter) of eternal life in transition. Her powers of protection are thus given to the sun barque of Ra upon entry to the Duat at dusk or twilight, at the commencement of the journey through night.
Nephthys, as drawn by Jeff Dahl
The words and spells of Nephthys are vital for passing safely through the underworld, for demons tremble in fear at her utterance. At dawn, Ra is greeted by Isis. It is said in the Pyramid Text Utterance 222, line 210:
Ascend and descend; descend with Nephthys, sink into darkness with the Night-bark. Ascend and descend; ascend with Isis, rise with the Day-bark.
(Ancient Egyptian Pyramid Texts, R.O. Faulkner, Oxford University Press 1969.)
Qabalistically, Nephthys is referred to Geburah, the 5th sephira of the Hermetic Tree of Life, and is the counterpart to Isis, who is placed in Gedulah. The pair embodies the Pillar of Force (Isis) and the Pillar of Form (Nephthys). The sisters are the inner power of the Sun and the Moon respectively and are the personification of the waxing and waning Moon (on each side of the Tree). Nephthys, as the waning Moon, symbolises the dissolution of the mind-ego complex and its identity with the personality. This is necessary before the word of the Holy Guardian Angel in Tiphereth can be received. Thus Aleister Crowley said, of the number 71 (in his 777): “A number of Binah. The image of nothingness and silence which is a fulfilment of the aspiration.”
