It is more like energy. H appiness is an emotion. Happiness and joy are not the same, though the words are sometimes used as if they were.
Happiness is a personality reaction.
It is the contentment of your personal emotions, and it disappears when you are disappointed. The search for happiness alone ties you to always seeking your pleasure and avoiding pain. Happiness is the goal of the separated self. But joy can flow through you even in adverse circumstances. I said earlier that unconditional love reveals itself through joy.
