Material for prisoner

by Susan
(FL)

Do you know of any good, easy-to-read material to send to my son in prison? He is asking for material on controlling or knowing your mind. The book he is requesting is about Buddahism(Know your mind). I want to send Christian material. He was raised Baptist. He has also mentioned Pagan, The Golden Dawn (A. Crowley), black magic,occult . I want him to put good Christian material in his heart and mind. I am not familiar with any of the books he has asked for and is being influenced by other than what I read on the internet.
