Having received bunch of emails from people who have read this book, but still had difficulty applying the principles in this, I felt compelled to share few ideas.
First, the principles in this book are correct and they work if you apply them. The book is about using the power of your subconscious mind. As I read over some previous reviews here, I noticed that some people stumbled upon the language and pointed out that one should read "As A Man Thinketh" (yes, it is a good book to read), and made a reference to "as you think in your HEART" - not mind. Another name for the SUBCONSCIOUS is HEART of the MIND, because SUBCONSCIOUS MIND is the REALM OF EMOTIONS.
Some people also erroneously think that the subconscius mind is in one's head, it isn't. It is not even confined to your physical body, but permeates it. Your physical body is IN your MIND. Another way to describe the subconscious may be to refer to it as your "energy field" (that may be somewhat more modern "language"). Do not get stuck to words and labels, though. They are merely useful to help describe things - they are not the experience itself.
To use self-hypnosis successfully, to use the power of your mind successfully, it is not enough to just repeat the words mechanically (although, with a lot of repetition, they too will be impressed upon your subconscious mind), but you must also use your feelings - EXPERIENCING the outcome you desire AS IF it were REAL for you now - subjectively.
The term subconscious mind is used to refer to your own individual storehouse of knowledge and memories. The term "superconscious", or "universal mind", "God", and sometimes in hypnosis the term "unconscious" are used to refer to the infinite storehouse of knowledge, which you access through your subconscious mind.
There is ONLY ONE Mind, but for the convenience we have divided it linguistically into three minds, according to its functions - conscious, subconscious and superconscious. You can imagine that there is one door standing between your conscious and subconscious mind and another between your subconscious and superconscious. You access both your subconscious and superconscious by getting the critical faculty of your conscious mind out of the way and the easiest way to do this is by fully engaging your imagination and your emotions.
Because you access your subconscious and superconscious mind in the same way, people sometimes just use the term "subconscious" to refer to both functions. Instead of using the world superconscious, Murphy sometimes uses he word "God" - which I like, but some people feel very uncomfortable with due to their religious upbringing or lack of understanding and direct experience (A Course in Miracles is one books that may help in that respect).
Your conscious mind is that part of your mind that judges things and contemplates whether you can or cannot do something. It compares things and when you attempt to use your conscius mind and work on some goal, it may pop up with all the reasons why something may not be possible for you to do. Your subconscious mind goes for DIRECT EXPERIENCE. It doesn't judge whether something is possible or impossible, good or bad - it merely ACCEPTS as true and real whatever you EXPERIENCE as REAL subjectively.
When you pick a goal to work on with your subconscious, make sure that it is something that is BELIEVABLE to you. Whatever ideas you desire to impress upon your subconscious mind will work in conjunction with that which is already in your subconcious mind - so if the ideas and beliefs which are currently in your subconscious are in conflict with your desired goal, it will take you a long time to experience the desired results. If you begin with things you are willing to accept as possible for you, you'll get much faster results and you'll also condition your mind for success and to the world of many new wonderful possibilities.
Also, keep in mind, that you are in one way or another programming your subconscious mind with every thought you think. So, if you are using self-hypnosis to help you create greater abundance and you are working on your goal for half an hour a day, then you spend the other 23 hours contemplating how you don't have money to pay the bills, you're just undoing all that work you invested in self-hypnosis. Once you are done with your mind-programming, whenever you think of your goal, you'll make it happen much faster if you spend time expecting the positive outcome and giving thanks that what you desire is already yours, or at least that it is on its merry way to you.
This lovely book teaches you how to use the power of your mind in many different areas in your life. It also provides examples from the lives of others who have successfully used the power of their mind to overcome numerous obstacles and create what their hearts desired. This little stories may serve you as an inspiration until you have an assortment of your own success stories to tell - and if you genuinely apply the principles in this book, you'll have many great stories of your own.
