I thought the True Name thing was Egyptian.
For instance, in Egyptian mythology a woman named Isis learned magic and the trick of how to turn a snake into a stick. She left the poisonous
snakestick where a God (Ra or Amen, I don't remember) would walk out in the morning. The snake revived and bit him. He called for other Gods to come rescue him. But the woman came right to his side and said she could cure him but had to know his True Name. He did and she, by speaking it, gained Godly power and became (or became one with) the Goddess Isis.
Besides snakes into staffs and reverse, another power attributed to Egyptian magicians was the power to part waters so they would stand like walls held back by force fields.
BTW, Ptah created the Earth in 7 days.
Egyptians had purification rituals of someone immersing himself in the Nile.
The ancient Egyptian temples remained open until a Christian Roman Emperor closed them. One Egyptian Christian, Anthony, became a hermit meditating in the desert when he was set upon by demons. His demons are portrayed as a mixture of animal and human -- which is the Egyptian representation of their Gods and demons. Demons had been regarded as dark angels but were portrayed as monsters afterwards.
