Em-hotep to all!
I've thought of a funny trick, but with deeper meaning in it.
He means ACTIVATE. Ka means kind of Soul. And I thought, so magic is Activating your Soul/Ka, so you get access to the plentiful spring of Magic of Atum-Ra or Osiris.
But I thought some things were missing. I noticed that Osiris and Isis were both master magicians. So they practiced as gods a high form of magic.
That's why I added -He behind Heka (my obsession really). I did this to give it more Power (double the words). So it becomes: He-Ka-He! Activate-Soul-Activate at a high level.
I practised this magic on my sister to heal her heart, mind and soul. I practiced good speech as many wise man and women in ancient egypt did. I give her hugs, gave compliments, talked about optimism and that things are going better in Africa. These things I dreamed in my heart, and uttered through my lips to my sister. And they worked like magic!

(And that's a good thing, because my sister was close to suicide, very close, she called for a Euthenasia in holland here. Terrified me).
Anyway, I wanted to share this with you all.
In the name of Atum-Ra, Osiris, and Thoth, the thrice great, great, great.
Em-hotep!
