What is Goodness?

We want a world where nobody is ever harmed - at least not too much.
And we believe that that is goodness.
But it is not goodness.
Lack of harm does not necessarily reflect goodness.
And oftentimes, our attempts to prevent harm cause harm.
So what is goodness?
Love, I think, is goodness.
And it must reside within the heart.
And though it reside within the heart, still, it cannot prevent harm,
Except within the soul of him that loves.​
