A Shikigami is a spirit created by a magician to fulfill any specific purpose or spell. Shikigami haunting was originally a spell meant for cursing or baneful actions such as spying or espionage, but you can cast it on yourself with positive intention just for the creation of a spirit companion. Casting this curse on yourself requires care and respect for the process and the deity you are creating.
You will need a caffeinated drink and some surface that can be poured over like a stone tile or a piece of wood. You will also need something like chalk or marker to draw a sigil for your shikigami. For creation of spirits, a basic circle or a circle with an X inside of it is the best way to start, because another one can be channeled later after the creation of your spirit.
Once you draw the sigil on stone or the floor somewhere, pour the caffeinated drink over the sigil. Other drinks work as offerings afterwards, but during the spirit’s creation you must make sure that the shikigami is awake to listen to its programming. Using either caffeinated drinks of even tea or coffee bean powder, pour it onto the sigil. Make sure you say immediately afterwards “You are a shikigami. Welcome to the world.” Do not say they are your shikigami or anything that implies ownership, as this can be perceived as enslavement later on and cause them to attack you. Also avoid any negative remarks as the new being is easy to influence in this state. Even music is not recommended unless you carefully analyze the lyrics for anything resembling negative emotion.
Programming the shikigami is the last part but honestly the most important. The first things the spirit sees or hears will be the basis of its existence. Do not say anything negative or that promotes helplessness. Negative energy at this time will create an evil spirit but this can be prevented by playing frequencies, mantras, or using the energies of another deity to allow it to form. You will begin with an energetic copy but other experiences such as environment and its own free will cause it to develop a more unique being.
Do not play with a shikigami or use them as a weapon because they can kill you, even if they don’t know how to immediately. Especially if you do bad things to them, these spirits have the power to murder people and they can’t go to jail because they are spirits. Do not make evil shikigami or abuse them or you will suffer at their hands.
