I came across this quote today, and it was the perfect reminder of what could possibly be the best motto for living a good life there is: do justly, love mercy, live humbly.
This quote comes from The Talmud (if you are unfamiliar, it is a book of Jewish oral law, wisdom, philosophy, and logic that is referred to as the "central pillar" of Judaism). Unsurprisingly, there is a very similar verse in the Old Testament of the Bible: "Seek justice, love kindness, and walk humbly with your Lord." (Micah 6:8)
I'm sure many other faiths have similar passages, and if so, I would love to hear them.
There is so much good in these words:
There is enormous grief in the world.
You will want to let it overcome you. Do not.
Neither can you do nothing. Act, right now, with justice, mercy, and humility.
Do not become tied to an outcome, simply do the right thing.
