Book Summary - 'The Master Key System' by Charles Haanel

Charles F. Haanel
The Master Key System is a personal development book by Charles F. Haanel that was originally published as a correspondence course in 1912. Though originally a 24 week correspondence course, it was published in book form in 1916.

The Master Key System is the source of Rhonda Byrne's inspiration for the book and the film "The Secret" (2006). Charles F. Haanel was an American author, millionaire, entrepreneur, and businessman who belonged to several Masonic societies, the American Scientific League, The Author’s League of America, The American Society of Psychical Research, the St. Louis Humane Society, and the St. Louis Chamber of Commerce.

Napolean Hill, the author of "Think and Grow Rich" also credits Charles Haanel and this book for his success. I have summarized the 24 parts of the Master Key System. I have collected the main points which have helped me. Hope this helps you also !

Given the busy lives we lead this can be a quick reference to whenever I want to feel good instantly. Until you really try to exercise what has been written you cannot become or achieve what you want. Pay special attention to the exercises at the end of each Summary. It is a system, enjoy it !!

Lets get started !!

What is the Master Key?
The Master Key develops Mental Power which means that others instinctively recognize that you are a person of force, of character - it means that you attract things to you; that you are what some people call "lucky", that "things" come your way' that you have come into an understanding of the fundamental laws of Nature, and have put yourself in harmony with them; that you are in tune with Infinite; that you understand the law of attraction, the Natural laws of growth, and the Psychological laws on which all advantages in the social and business world rest. 

Thoughts of courage, power, inspiration, harmony, are substituted for thoughts of failure, despair, lack, limitation and discord, and as these thoughts take root, the physical tissue is changed and the individual sees life in a new light, old things have actually passed away, all things have become new, he is born again, this time born of the spirit, life has a new meaning for him, he is reconstructed and is filled with joy, confidence, hope, energy.

  6. excellent I love this teaching and am also working through it... I have an online community discussion of it that everyone is welcome to join at The Master Key System - Online Discussion Community I would encourage anyone to come and talk about this teaching.

  7. I should mention to your readers that you have unfortunately posted the "altered version" and not the original teaching - unless of course you believe there was VCR's in the early 1900's.

    This is simply a recopied version of the free pdf available on "The Secret" website.

    Still a good read but not the original source something you have to be aware of with these "Public Domain" works.

    I'm excited to share this with you.

    The MKS isn't Haanel's most powerful book.

    I've discoverred the Psychology of Business Success, which seems to me like an evolution of the MKS. It has been published in 1930 (so 18 years after the first MKS lessons were sent) and it is easier, faster (16 lessons instead of 24) and more powerful than the MKS.

    Click on my name to check it out.

    Hello Ash:

    Thanks for the summary! Nicely done!

    Charles Haanel's "The Master Key System" is one of the greatest courses on success that was ever created. Charles Haanal was a genius.

    Applying "The Master Key System" to life causes REAL changes to occur!

  12. Thanks for your beautiful summary. I will like to point out, though, that there are 28 parts to the original 24 parts of The Master Key System By Charles Haanel (The 28 Part Version Is The Complete Version of The Master Key System). The missing 4-parts are the most powerful parts of The Master Key System. Not too may people know this. Read my blog:

  13. I was given a copy of The Master Key System one year ago. I work in a metaphysical bookstore. I am so pleased with my own progress, I have sold 117 copies of this book in less than 12 months.
    I'm happy to be part of a "NEW" and growing group of enlightend beings putting these lessons to use.
    Perhaps Salmon Arm, will become the new home for Charles Haanel fan club?? A discussion area for new readers. Blessings to Haanel whereever he is. Such a lefe changing book.
    thank you or the time and space.

  14. Thank you for this!
