Your mind: it is your constant companion. You live with it 24 hours a day, every day of your life. Yet Man has known practically nothing about how it works. And from marriages that end in divorce to careers that wind up in frustration,from tensions that interfere with work to conflicts that divide nations, virtually every human crisis can be traced to Man's ignorance of the mind.Imagine, then, the potential benefits of finding the answers. Not only could organizations prosper and nations resolve their differences, but anindividual equipped with such knowledge, fully understanding himself and others, would stand a far better chance of achieving his goals. In fact, millions have accomplished exactly that. For the first time in history, Man has come into possession of an "operation manual" thatdetails the full anatomy of the mind and precisely how it functions. By studying this "manual," anyone can understand the underlying causesbehind the endless variety of human behavior and use this knowledge to resolve any situation he encounters in life. Here, then, is the adventure of discovering the workings of the most valuable commodity any individual will ever possess.
