If we can learn how to create space for action without losing touch with the joy in our hearts, we can live with serenity. We become stressed, anxious, and depressed because we have limited our minds to act and react according to our psychological, emotional and physical aspects only.
Think of it this way; when we are in our hearts, living a kind and positive life, we can be overloaded with thoughts and physical activities, and our peaceful state won’t change as long as we are not identified with our "must do" actions, and likes and dislikes, but rather open beings that embrace it all. What is amazing is that we can live in that space, starting at this moment, by recognizing we are joyful and serene beings having a human life!
To be healthy is to be loving.
