Happiness

Happiness is the emotional state experienced when we express love. It is so elusive because we so often change our expressions. Our expression can change as often as the thoughts go around in or mind or when we have a reaction. That reaction is then our expression of emotion that we feel. When we express love, we feel the joy of that expression.
When you master expressing love, you master being happy in your life.
