An excerpt from The Mind: Its Projections and Multiple Facets by Yogi Bhajan (page 79)
Your mind is designed as a preparatory system to guide and aid your life. It is a power to gather your resources and shape your behavior. You can refine the mind, its Facets, and all its combinations. Then you can act effectively in your Executive Mind, Creative Mind, Applied Mind, and hundreds of others. But you must train and refine the mind to give you those Functional Minds that serve you and your soul.
The mind forms patterns based on habits. Those habits are woven from our attention and from our thoughts. To break the shackles of low thoughts and habits, we have the ability to dwell in the vastness of our soul. By enriching and refining the mind and its Facets, we form a relationship within us that supports our projection to lead and contribute to the world.
