A while back, one of my friends posted something on Facebook which resonated with me -- a quote which suggested that we never know when someone is facing something difficult or painful, or carrying some hidden grief, and so the most important thing is to be kind.
When I did a google search, trying to find the quotation in question, I found "Be kind, for everyone you meet is fighting a hard battle," sometimes attributed to Plato, sometimes Philo, and other times to John Watson -- not the Arthur Conan Doyle character, but the reverend. (For more on this: Be kind, for everyone you meet is fighting a battle - quoteinvestigator.com.)
I've seen a variation on this idea raised in response to various online imbroglios. If someone doesn't reply to your comment right away, don't assume that they're ignoring you; if someone posts something distressing, try to give them the benefit of the doubt; you never know what's going on in their life behind the privacy of the computer screen.
But even in person, I think it holds true. We never really know all of what's arising in someone's head and heart, or what anxiety or sadness they may be carrying. A fear, a difficult diagnosis, distance from a loved one, regret... we hold a lot of things in our hearts, and many of them are not easy to sit with.
In such a situation as this -- and this is the situation in which we all live, whether or not it's particularly acute at any given moment -- what could be more important than being kind?
One of the commentors on that quoteinvestigator post noted that this is very like a teaching from Mahayana Buddhism. To wit: suffering is pervasive; we compound our suffering by forgetting that we are interconnected; the way out is to recognize our interconnectedness and to treat everyone with kindness.
In my religious tradition we say that chesed, lovingkindness, is one of the fundamental characteristics of God -- and as we are made in the divine image and likeness, lovingkindness is an essential human quality, too. "On three things the world rests," says one of our aphorisms: "on Torah, and on avodah (service / prayer), and on gemilut chasadim (acts of lovingkindness)." Without acts of lovingkindness, the world would not endure.
It's not always easy to respond to the world from a place of chesed. I am reminded of this daily in a hundred tiny ways. Our child dawdles getting dressed and I risk being late to meet someone. Someone sends an email which agitates me and makes me angry. I hear something on the news which raises my ire. I don't always manage to respond in the way I might wish.
But it's a goal worth aiming for. Because we all suffer, and we all carry wounds both old and recent, and we all yearn to be met with kindness.
