Query: The Scientology Sales bible

This is the Scientology sales book, also known as 'Big League Sales'. If you are a Scientology staff member for very long, eventually you will see this book, either in this form, or a photo copy. This is the book that they use to train all staff on how to hard-sell Scientology services and materials to the masses. This is one of the few books that LRH mentioned and liked so its now permanently part of their teachings. It is a very short and crappy sales book, that can be read cover to cover in an hour or two. It is very basic and does not have many examples or techniques. Thousands of Scientologists all over the world have been drilled on the techniques in this book. Don't waste your money, just get a more modern sales book that is more well known and has more and better examples. This book is set in the 50's or 60's if I remember correctly so it is very out of date, and a lot of the advice in this book is not relevant to the 21st century.
