"In closing, I would like to thank all these disciples who have so kindly placed their personal instructions at my disposal in an effort to be of service to the coming generation of disciples. In many cases, they helped prepare them for the press. I would like also to thank those who helped me to get the text ready for publication, particularly Joseph Lovejoy who gave days of labour to the book; he has for years helped me prepare the Tibetan's books for publication."
