Good Day.

TO SUMMON A DEMON HELPER
Time:
Midnight on a Saturday.
The dark of the Moon. Place:
Cemeteries, Haunted Places, etc.
Items needed:
black candles,
brimstone (or any other "dark" type incense, black arts etc.)
black onyx (Black Onyx was believed to already possess a spirit so this is why I use it but you can choose any black stone of your choice.)
Sterilized needle.
Disrobe.
Arrange black candles in any pattern one may wish, pentagram or what not.
(I use graveyard dirt to draw a pentagram and then place black candles at each cross point.)
Light the brimstone as incense.
At midnight chant:
"IT IS MIDNIGHT.
THE GATES OF HADES ARE OPENED AND DARKNESS IS UPON THE LAND"
*3X Hold the stone in your left palm.*
"I CONJURE THEE DEMON BY THE POWER OF THY NAME;
ABSHALLAH NEJAR SEPTIA,
AS FLESH CLINGS TO BONE SO YOU TO STONE!
*If done properly you should see with your mind's eye a purplish "lightning" dance around the stone.*
*You must never let sunlight hit the stone or the spirit will return from which it came.*
*You can ask of your demon anything but alas, it seems that the relationship is not permanent.*
*If you demon fails to comply with your wishes it may be time to exile it.*
*I've notice that threatening to place the stone in the sun sometimes works to "compel" the entity but if it becomes violent immediately cast it out into the daylight.*
*You must reward the demon by feeding it three drops of your blood after if fulfills any of your wishes.*

I would be weary or making an open invitation for any demon to come and visit, especially with the symbolism employed in that ritual. I would further be in disagreement with offering your blood to something which you do not have, or have no intention of making, a relationship with.

Thanks for answer.
I think,that negative Entity shouldn't appear.And if happans so,it would be under control of Operator/Mage by the Power of Ritual.I also think that this Ritual We Can Change Somehow.I mean Operator can say the Concrete Spirits Name wich should be Taped into Stone...For example someone from Goetia,Someone not aggresive for begining...
Ashnook,What Can you Say about this Change?

Demons are not necessarily negative beings (atleast not for me). They can have a similar sense of humour as humans do, and they don't like to be treated with disrespect. Im not saying you direspect Demons or anything, but what im saying is that they are misunderstood usually by new age occultists and are often mistreated, and when a negative incident happens because of this, they are convinced that Demons are "negative", which is not true.

My suggestion to you is, know what entities you're working with, especially for summoning, before you work with them or summon them. And just because they are "said" to be negative, don't take it too seriously until your research says they are.

Good Evening.
Thanks for your Advices and answers My friends (IMG:style_emoticons/default/smile.gif)
