Why are you so happy all the time?

Here is a picture of one of the many forms of Maitreya. The very happy Buddha many of us have seen depicted. It was the first Buddha gift I received (from Taiwan) in 1969. So he has been hanging out with me for awhile and teaching me about happiness.
Why is he so happy all the time? He is expressing the great joy he has in relieving living beings from suffering. Like any representation of a Buddha it is meant to reflect a naural state of being which You already posses.
Yesterday I read a quote from the Spirituality and Practice website (see links) that brought me some understanding. "Most of the harm done in this world is the result of people who are compensating for deep insecurities, who are trying to "prove" something to someone..." (quote from Robin Meyers). Aha, this makes sense. Just reflect on the people in your own life who may be causing problems. The constant striving to prove their own "worthiness" may shed light on the root of their behavior (and our own at times).
Maitreya Buddha reminds us of our own worthiness, own own lovliness and lovability. Nothing to prove. No striving. Accepting our own worthiness can greatly help to relieve suffering and reduce harm.
When you have time click on the Tibetan Sand Mandala. The chanting is the heart of Maitreya.
