Joy is that kind of happiness that doesn't depend on what happens. Normally, we are happy when something good happens, and we are unhappy when something happens that we do not consider good. We pick and choose. But joy is our wholehearted response to whatever opportunity is given to us in any moment. It does not depend on what happens.
