Peace of mind. True freedom!

The main way to achieve and maintain a settled mind is by being happy. This is because when a person is happy, he can direct his mind as he wishes, and he can settle his mind to think about the ultimate, eternal purpose of his life. For joy is the realm of freedom, and consequently, when a person bunds joy to his mind, his mind is then free and not in exile. Then he can attain a settled mind. Abridged Likutey Mohoran 2:10:2
