The intro looks straightforward enough to me. I was thinking two things though, it might be useful to have the Appendix A of recommended reading scanned as well and stuck to the top of the forum. Also, for those of us who are not intending to buy the book, I was thinking that another type of CD that might be useful is one that is designed to increase theta brainwaves (for meditation). My local metaphysical bookshop has some CD’s that do this, I listened to one once and it was really odd what it did to my head. It could be worth experimenting with.
