There are several different kinds of painful feelings that we might experience, and learning to distinguish and relate to these feelings of discomfort or pain is an important part of meditation practice, because it is one of the very first things that we open to as our practice develops.
Jack KornfieldGratitude is the confidence in life itself... As gratitude grows it gives rise to joy. We experience the courage to rejoice in our own good fortune and in the good fortune of others... We can be joyful for people we love, for moments of goodness, for sunlight and trees, and for the very breath within our lungs. Like an innocent child, we can rejoice in life itself, in being alive.
