The mind exists as a servant to the soul.
Your mind is constantly in motion. It has no base or fundamental reality of its own. It requires your direction. In order to act and create you must use the mind, but the mind can also use you.
When your mind is balanced and refined, it serves your soul and consciousness. But you need a habit to relate to your mind. You need to create a relationship with your mind. You need to sit with your mind and review it, polish it, and direct it in meditation.
Your soul has a fundamental property that, when aligned with your mind, gives you impact, intelligence, and effectiveness.
Your mind is your projection. If your mind is with you, it acts as your leverage, it is your powerful friend.
Success, happiness, and a flow of prosperity are the result of mastering the mind.
