The Master Mind is a concept developed in “Think and Grow Rich” by Napoleon Hill. I consider this a masterpiece! Here is an excerpt from the book that I think you’ll find helpful. Not only does it perfectly sum up the power behind a true Master Mind experience it also exemplifies what I have seen with my own eyes while facilitating Master Mind groups for the last 20 years.  

“Great Power can be accumulated through no other principle than that of the Master Mind!”

P 183 “Economic advantages may be created by any person who surrounds himself or herself with the advice, counsel and personal cooperation of a group of people who are willing to lend wholehearted aid, in a spirit of PERECT HARMONY. This form of cooperative alliance has been the basis of nearly every great fortune. Your understanding of this great truth may definitely determine your financial status.”

“No two minds ever come together without, thereby, creating a third, invisible, intangible force which may be likened a third mind.”

“Keep in mind the fact that there are only two known substances in the whole universe-energy and matter. It is a well-known fact that matter may be broken down into units of molecules, atoms, protons, neutrons, and electrons. There are units of matter which may be isolated, separated, and analyzed.

Likewise, there are units of energy.

The human mind is a form of “energy,” a part of it being spiritual in nature. When the minds of two people are coordinated in a SPIRIT OF HARMONY, the spiritual units of energy of each mind form an, “affinity,” which constitutes the psychic phase of the Master Mind.”

“It is a well-known fact that a group of electric batteries will provide more energy than a single battery. It is also a well-known fact that an individual battery will provide energy in proportion to the number and capacity of the cells it contains.

The brain functions in a similar fashion. This accounts for the fact that some brains are more efficient than others, and leads to this significant statement: A group of brains coordinated (or connected win a spirit of harmony will provide more thought-energy than a single brain, just as a group of electric batteries will provide more energy than a single battery.

Through this metaphor it becomes immediately obvious that the master mind principle holds the secret of the POWER wielded by people who surround themselves with the minds of other capable individuals.

When a group of individual brains are coordinated and function in harmony, the increased energy created through that alliance becomes available to every individual brain in the group.

Individuals take on the nature and the habits and the POWER OF THOUGHT of those with whom they associate in a spirit of sympathy and harmony.

When two or more people coordinate in a spirit of HARMONY and work toward a definite objective, they place themselves in a position through that alliance to absorb power directly from the great universal storehouse of Infinite Intelligence. This is the greatest of all sources of POWER. It is the source to which the genius turns. It is the source to which every great leader turns, whether consciously or not.

When money comes in quantities known as ‘the big money,” if flows to the one who accumulates it as easily as water flows downhill.  There exists in life a great unseen STREAM OF POWER which may be compared to a river-except that one side flows in one direction, carrying all who get into that side of the stream onward and upward to WEALTH, While the other side flows in the opposite direction, carrying all who are unfortunate to get into it (and not able to extricate themselves from it), downstream to misery and POVERTY.

Every person who has accumulated a great fortune has recognized the existence of this stream of life. It consists of one’s THINKING PROCESS. The positive emotions of thought from the side of the stream which carries one to fortune.

Understanding that you yourself can control where you will be in this stream of life is of stupendous importance!”
