This book explores the pivotal place of the fiery serpent-eye goddess, Hathor-Sekmet, in the mysteries of Osiris, the Egyptian god of the dead. Weaving together myths, rituals and temple art, it recreates the craft world of ancient Memphis, with its heart-centred religion and vitalising feminine divinities. The author reveals the rich and complex temple life of New Kingdom Egypt in a compelling account of the soul’s return to primal origins in the Ancestor Ritual, a little known royal death and rebirth ceremony. My Heart My Mother breaks new ground with its analysis of Egyptian sacred architecture. Seti I’s temple at Abydos is shown to be an image of heaven, built to correspond with the cosmic ‘maps’ of living and dying depicted on the remarkable Nut ceilings in Theban royal tombs. Each part of the Abydos temple is a focus for transformation in the ancestral rites. Despite great social changes this heart wisdom continued long after the rule of Pharaohs ended. The book traces its profound influence in alchemy, presenting fresh evidence to support the alchemists’ own belief in the Egyptian roots of their tradition.
