I want to know if I am on right hand path but if I will try to evoke any demon,lilith or Lucifer etc.the will they hurt me,will they torture me?
No they will not! Anyone can evoke them! All you need is respect! That means lose the threats!
Yes, you can still evoke them.
The Ars Goetia and the rest of the Lesser Key of Solomon is actually RHP magick, after all.
Spirits are not restricted to LHP or RHP (white or black if you want to go that far). That’s all human. So, yes you can evoke demons while being a white magician.
