I have attempted to evoke before with two black candles and a sigil. I don’t even know if the entity was there or maybe an entity was impersonating it.
I never thought candles were necessary or even the sigil to successfully evoke the spirit. Because the doubt doesn’t exist, I can believe more and it work. I can probably do it lying in my bed and just thinking about the entity.
I just need to know if I really am talking to it.
