The bible talks about being careful of the company you keep. The scriptures says in 1 Corinthians 15:33 King James Bible, be not deceived: evil communications currupt good maners. Have you ever been somewhere with a group of people and everything was going just great until a certain person showed up and all of a sudden the entire atmosphere changed and people attitudes began to change? Well once you read this book you know just how that happens and how transfering of spirits operate in this physical world. This is not some kind of spooky, superstious teaching, this is concrete biblical proof of spritual activity in our physical world.
