PEACE:
The biggest mistake people make within Kemetian Theology, is to presume that a name that is read or discovered, constitutes a historical person.
This is not correct.
Ani is a Kemetic word that means "I am". Thus, ANI as mentioned in the Pert is a recitation meant to be spoken by whomever reads the texts.
As you read the text, you see the spiritual adventure that ANI undertakes; communing with, and eventually becoming the God(ess)s that he and his wife THUTHU (which means "wisdom") meet on their travels into the realm of the spirit.
