I have read many many books, most of them are messages of wisdom and spiritual philosophy channelled from higher spiritual entities. I myself is also learning the art of channelling, so I know it's real. Please read these books and take what resonates with you and leave the rest behind. Our intuition is a great tool that helps us remember what we already know. When something rings true to you, it is your higher self remembering what you already know and deservingly learnt. Not everybody is ready to receive or understand all knowledge which is written in books, but if you read it now, it may sow a seed that will grow later. What makes no sense now, may ring like a proverbial bell 4 years down the line. On Lee Caroll's and Kryon's defence they are not exploiting, they are covering all bases in trying to reach people in everyway possible. You don't have to buy these books or audio tapes to read their wisdom as they are freely available on their website. They travel to many places spreading hope for humanity. If this was for greed, then they wouldn't publish the teachings for free, even letting people publish them on their own websites without permission. Being spiritual is about finding the truth within you and nobody else, so make your own mind up. God Bless.
