Hi Kev,
I also had many questions when studying QGong. The more I get to know Master Lin, the more comfortable I feel with his teachings. He is truly dedicated to teaching us and has spent many years studying QGong, not to mention the information he receives while meditating. So, I decided to follow his teachings on faith, not understanding. It seems to work for me.
About his first book, a limited number was available for sale this last weekend at the SFQ Association meeting. I understand a new, revised edition will be available March, 03. The name of the book is "Born a Healer". I think you can still order this book by calling Tom Jazdzewski at 612-581-6524.
Good luck with your QGong practice. Joana
