A mastermind alliance as described in Think and Grow Rich has significant benefits. This group is for spiritual beings who are like-minded individuals. The benefits of a mastermind alliance are significant. One is economic and the other is psychic. Economic advantages may be created by people who surround themselves with the advice, counsel and personal cooperation of a group of people who are willing to lend them wholehearted aid in a spirit of perfect harmony.

Great power and achievement can be accumulated by no other principle!
