It is easy to love the people who already love us back. A child, a partner, an old friend — the warmth flows without effort, because it is met with warmth. The harder question is what happens to that same warmth when we picture someone who has hurt us. For most of us, it simply stops. We can be endlessly kind in one direction and quietly closed in the other, and never notice the wall, because nobody makes us stand in front of it on an ordinary day.
Buddhist practice has a name for the warmth itself, before it gets directed anywhere: the mind of loving-kindness. And it makes a claim that sounds almost like a technical instruction rather than a moral one — this mind has to be full before it can be spread. Not felt in theory. Full, the way a cup has to be full before it can overflow into anything else.

The Buddha’s teaching on this is old and specific. In the Karaniya Metta Sutta, a discourse in the Sutta Nipata, monks who had gone into a forest to meditate were so unsettled by what they encountered there that they returned to ask the Buddha for help. What he gave them was not a protection charm in the way they may have expected — it was an instruction to radiate loving-kindness outward, the way a mother guards her only child, until it reached every being without exception: the seen and the unseen, the near and the far, those already born and those yet to be born.
What is easy to miss in that image is the order it implies. A mother’s love for her child is not a performance aimed outward first — it is something that fills her completely before it ever reaches anyone else. The sutta asks us to build that same fullness, then let it widen: ourselves first, then the people already close to us, and only then further out, circle by circle, until it no longer has an edge. Practicing this way, the teaching is not really about people who are far from us at all — it is about not skipping the part where love has to be real before it can be that big.

This is also where the practice stops being comfortable. The most demanding form of it — arguably the whole point of it — is spreading that same loving-kindness toward the people who have hurt us, the ones we’ve quietly filed away as enemies. It is not difficult to love someone who has never cost us anything. It is a different order of practice to wish someone well who wronged us, and mean it, and want them to actually be released from whatever made them do it.
Because that is usually the missing piece: the person who hurt us was rarely acting from strength. More often it is someone unloved, mistaken, straining under a life that has already worn them down — and it is precisely that condition that produced the harm. Seen this way, anger at them starts to look less like justice and more like a refusal to look closely. We tend to place the entire cause of our suffering outside ourselves, in what they did, without asking what in us is still gripping onto it, still replaying it, still calling it unfinished. The other person’s actions happened once. Our holding onto them is a choice we keep renewing.

None of this is only about other people, in the end. Loving-kindness turns out to be less a gift we hand outward and more a fire we keep lit in ourselves — an energy strong enough to pull us back out when we’ve sunk into our own difficulties, because a mind occupied with wishing others well has less room left to drown in its own grievances. It costs nothing to notice that the people who manage to hold onto this practice, even imperfectly, tend to be the ones who seem lightest — not because life has spared them, but because they’ve stopped carrying quite so much of it as a grudge.
So the practice is not really “love your enemies” as a slogan to admire from a distance. It is closer to a question you get to answer again each time it comes up: the next time you picture the person who hurt you most, do you still have the fullness to wish them, honestly, a way out of whatever made them do it — or is the wall still doing its work?
A note on this article: “Spreading the Mind of Loving-Kindness” is inspired by and draws lessons from a chapter in A Peaceful Mind, A Peaceful World by author TG Minh Thanh, translated from the original Vietnamese. Among the many themes explored across the book, this chapter focuses on the practice of loving-kindness — including toward those who have caused us harm — as a source of inner peace.
