Dangers Of Chi
Dangers of chi is an interesting take on the whole satanic/jinn posession scenario but this time linked to the martial art (or internal art) known as Qi Gong (also Chi Kung). The site is run by an ex Qi Gong practioner who details his views and experiences based on actual events that occurred during his training and led to him being possessed by Jinn. If you read anything on this site, definitely read his story which can be found here.
The site does take an Islamic perspective in terms of solution but having read much of what is on this site and what we know about Islam and it’s acceptance of the concept of a species which lives in a parrallel world to ours i.e. the Jinn or DJinn it’s actually a very good read indeed.
