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. However, our peaceful state won’t change as long as we don’t identify with our "must do" actions (and likes and dislikes), but rather keep ourselves open to embracing it all. What is amazing is that we can live in that space, starting right now, by recognizing we are joyful and serene beings living a human life!
To be healthy is to be loving.
