Leraikha- Goetic Demon

I’ve gone trough the Mastering Evocation From 1 to 4. I’m still not that good at structuring and scrying but I’m still gonna try to call him to a essence and give my will.
I don’t have any temple so I’m gonna try to call him in my bedroom with no circle or other tools just a scrying mirror to see of I can see anything.

I won’t do any banishing rite, I’ll just say "I now purify this place in the name of darkness and in the name of Azazel."
Then “Zazas…Zazas…Nashatanada…Zazas”

Then I try to evoke him.

So can anyone authenticate this, please? I mean if I’m doing it right. Or Have I missed anything?
Thank you!
