Time for work. I buy chocolate bar as offering. I will look for all the Psychopomps I can find and give piece of chocolate. Me and friend will put all of will power into it. We will open sigil of psychopomps and underworld gods as @Micah suggested.
Here is list so far of spirits I can call so far to help.
any other suggestion. We hoping his suffering end soon. Hopefully spells will direct energy to his soul leaving. Hopefully the spirits will take out soul from body while sleeping and peacefully. It should be easier because he has no will at all to live. He has no desire to be here anymore. Everyday for month he visualize his soul leaving body and the astral cord getting snipped.
Any spirits you know who can cut astral cord?
I will be looking for sigil of these spirits today and chant mantra. I will open them up and give the offerings today.
