topic is great..... but i have learned one thing and what i know is that having a strong will, determination and faith in God is a great tool in vanishing or stopping demonic possessions..... to learn more about how to stop or practice demonic/spirit banishing or vanquishing, you better purchase the book entitled "CIRCLES OF POWER" . there are lots of techniques and practices you can learn to enhance your knowledge about this subject..I have one in my possession and other books that i have are mostly related to occultism......
