On shadows and then some

While walking home some days ago, some cars tried to trample my shadow. But it was my shadow that always won! Yet, it could lose. If it were on the wrong side of me...

Philosophizing this bit of physics, I inferred what the Mahabharatha says, characterizing Karna as it does. "Be on the right side. And you will win."

If only all things were that simple all the time. Or at the very least some of the times?

By the way, what is right? And what is loss? Does loss lead to sadness? And what is happiness?
