“ I believe the experiences reported in this book are reproducible by anyone who wishes to try. I went to Africa. You can go to Africa. You may have trouble arranging the time or the money, but everybody has trouble arranging something. I believe you can travel anywhere if you want to badly enough.And I believe the same is true of inner travel. You don't have to take my word about chakras or healing energy or auras. You can find about them for yourself if you want to. Don't take my word for it. Be as skeptical as you like.Find out for yourself. ”
