"When your longings center on things such
that sharing them apportions less to each [party],
then envy stirs the bellows of your sighs.

But if the love within the Highest Sphere
should turn your longings heavenward, the fear
inhabiting your breats would disappear;

for there, the more there are who would say 'ours,'
so much the greater is the good possessed
by each--so much more love burns in that cloister."

Purgatorio VI.49-57

I realized the other day that human happiness is not a commodity that decreases when others have it. I think that often we see other people who are happy and we might be tempted to think that we are missing out or that we somehow now are less happy because they are happy. I think everyone can be happy in their own way, with their own talents, and with their own futures that lie ahead of them. We have tough breaks for sure, but if we realize that we the reservoir of human happiness is bottomless, our feelings would be more in line with the above quote. A love that is turned "heavenward."
