I was in a meeting at the Pentagon recently, seated at a table surrounded by uniformed military officers and dark-suited government officials. The meeting was tense, with the officials all insisting the Defense Department was doing the right thing and I and my colleagues from other human rights organizations pointing to our evidence that in many situations, it had not. We didn’t seem to be making any progress.

At some point I glanced down at my wrist and realized I was wearing a red rubber bracelet that said in prominent white letters: “Self-Compassion It.”  I’d been given the bracelet upon completing an eight-week training course in “Mindful Self-Compassion,” and had been wearing it as a reminder to use the tools I’d learned.

Nothing wrong with that, right? Still, in this buttoned-up professional setting, I was instantly embarrassed. I sheepishly tucked my hand under the table, slid the bracelet off and stuffed it into my handbag. The idea that I would be seen considering “self-compassion” in a meeting of senior warriors seemed absurd.

The idea of mindful self-compassion can sound silly, trivial and self-involved. But it’s actually anything but.  As Kristin Neff and Chris Germer, the psychologists who created the Mindful Self-Compassion course explain, self-compassion has been scientifically proven to be critical to well-being.

Unlike self-esteem, self-compassion isn’t based on pumping yourself up to believe you’re better than anyone else.  That keeps you in a judging mindset, so as soon as you screw up, you feel worthless again.  Self-compassion is instead having compassion for yourself — not for your accomplishments, but simply because you’re a human being, flawed like everyone else, and deserving of compassion nonetheless.  Once you acknowledge that you don’t have to be perfect to deserve compassion, you naturally start feeling compassion for the other less-than-perfect people around you. In other words, it’s helpful not only for yourself, but for everyone you encounter.

Neff’s book, Self-Compassion: The Proven Power of Being Kind to Yourself, explains this all very well.  But most convincing to me was Neff’s story of how she’s applied it in her own life.

As a small child, her son was diagnosed with autism. She felt a huge range of emotions — including disappointment, sadness, grief and fear.  She had recently learned self-compassion techniques on a week-long mindfulness retreat. She describes how flooding herself with self-compassion allowed her to feel her full range of emotions — including the shame she felt at some of her reactions.  Only by accepting those emotions with compassion rather than judgment could she fully experience them, to the point where she could accept and then acknowledge that she was strong enough to handle the situation. Not that it was easy, but it gave her a critical tool to deal with the challenges.

After that, when her son would start acting out — screaming and flailing in public,  for example, as some autistic children do —  she would comfort herself for her feelings of confusion, shame, stress and helplessness. That calmed her enough so she could respond wisely and compassionately to her son, instead of lashing out in anger or wallowing in self-pity.

Neff’s experience illustrates why self-compassion is so valuable.  It allows us to face our situation, whatever it is, with compassion instead of judgment. That allows us to look at the situation more honestly and thoughtfully, and to choose more carefully how we want to respond.

If I’ve made a mistake, for example, instead of immediately criticizing myself as “stupid”, I can forgive myself for not being perfect, acknowledge the mistake, and look more closely to see what happened and what I’d want to do differently next time. Giving myself compassion instead of criticism allows me to move forward. On the other hand, if I immediately beat myself up and feel worthless, I’m going to try to hide from or forget the situation immediately and avoid looking at what I did at all.  And I’m more likely to repeat the same mistake again.

The feeling of compassion, much like the feeling of love, has positive physical effects on our bodies, too. Scientists have shown it increases oxytocin, which has a calming effect on our nervous systems; it improves vagal tone, which helps the body reduce inflammation; it improves relationships, which has an anti-ageing effect, and, well, it just feels good.

The feeling of judgment or self-hatred, on the other hand, creates anxiety, which has a decidedly negative impact.  Chronic self-doubt and anxiety harm the heart, immune and gastrointestinal systems. Plus they just make us feel lousy.

Compassion “involves the recognition and clear seeing of suffering,” writes Neff. “It also involves feelings of kindness for people who are suffering, so that the desire to help – to ameliorate suffering – emerges. Finally, compassion involves recognizing our shared human condition, flawed and fragile as it is.”

Self-compassion thus places us in the sea of common humanity and allows us to extend the same compassion to ourselves we would instinctively offer to a good friend, a small child, or favorite pet.  It allows us to acknowledge what’s happening, including our suffering, with kindness rather than with judgment.  For those of us who’ve allowed ourselves to be ruled by self-judgment, that’s a huge relief.

“Self-compassion provides an island of calm, a refuge from the stormy seas of endless positive and negative self-judgment, so that we can finally stop asking, “Am I as good as they are? Am I good enough?” writes Neff.

It’s hard to be a human being in a difficult world. Our social and professional settings can make us feel like we constantly have to prove ourselves, to measure up, to justify our worth. As obvious as it sounds, no one’s perfect: we all make mistakes, even if we’re trying our best, usually in less-than-ideal circumstances. The simple response of kindness – both for ourselves and for others – can go a long way.
