If we learn anything from the peace that is in us, it is that it represents the highest good to which no only persons but whole people can be called, and we cannot be content with our own serenity and, at the same time, indifferent to the swirls of anger that threaten to rend the fabric of society all around us. To do so would be to make of ourselves hypocrites, content to save ourselves and lose the world.
If your heart were pure then all of nature would be a great book of holy wisdom and sacred doctrine.
