Lately, I have been working with Spirits of the Dead in my rituals that involved hexing, and I was wondering what the practioner could offer these particularspiritual beings as thanks for working with me? I have read some legends about the Spirits of the Dead needing "blood" in return. I took the "blood" referenceas a term used for vital spiritualforces. For example, I feel like I could offer them a bowl of empowered water that's unpurified. I do not want to anger these spirits of the dead. Therefore I am asking if anyone had any suggestions based on fact, wisdom, or experienceon this matter of offerings after a working.
