The Land of Kam

In Kemetic (ancient Egyptian) lore, Oset (Isis) poisoned Ra with a magical snake so that she could learn his secret, hidden name and have divine power that she could use to protect Hru (Horus). When Oset asked Ra to tell her his secret name so that she could heal him of his afflictions. Ra responded by saying:
“I am KhepeRA in the morning, I am RA at noon, and I am Tmu (Atum Ra) at evening.”

When the different aspects of Ra are syncretized with the Dikenga dia Kongo according to their solar position.  Ra’s response indicates that his hidden name is Amun Ra (the Hidden Ra) and that Ra is not the sun god but symbolizes the moment of the sun from the Kemetic perspective, hence the Maa Aankh cosmogram.
