I have a real close friend who is sooo intellectual and lives in his head and has a limited emotional intelligence. He is very open minded and respects me and my journeys into the astral ect. He has asked me for a book so he can understand and try himself.

He would love to be able to try but first I need a strong academic book that would entice him. I am reading at the moment "the Multidimensional Human" by Kurt Leyland,. Which is easy for me to read and I am no way academic. Any suggestions much appreciated.

Thanks Ewo
