Giving life a point is a human creation. The dog, the tree, the rose do not live with a point. They simply live. They don't live for, like us humans do, they just live.
It is in our "living for" that we find perceived happiness, but that happiness is only temporary. When what we "live for" dies (literally and/or metaphorically) we fall tremendously, unable to exist without that thing which we depended on so heavily for our happiness.
When one can live, not trying to achieve or gain anything, without a point, then there is that happiness that can not be taken away.
