What is karma?

Judaism doesn't use the word karma, but it has spent thousands of years thinking carefully about the very thing karma points toward: the relationship between what we do and what happens to us, and whether the universe is ultimately just. The tradition approaches this not as an abstract puzzle but as something every person feels in their bones when they watch the wicked prosper or the righteous suffer. It refuses to offer easy comfort, and that refusal is itself a form of integrity.

The closest Hebrew concept is often considered to be *middah k'neged middah*, which translates roughly as "measure for measure." This is the idea that consequences tend to mirror actions in a morally coherent way, that how you treat the world has a way of coming back around to you in a fitting form. You find this principle running through rabbinic literature, in the Talmud and the Midrash, where the rabbis noticed patterns in biblical narratives and drew out their ethical logic. It is not quite karma, because it is not a mechanical law of the cosmos operating on its own. Rather, it describes how God's justice tends to express itself, often in ways that feel almost poetic in their precision. The punishment fits the crime, the kindness finds its echo. But the rabbis were also honest enough to know that this doesn't always seem to happen, at least not in ways we can see.

This is where Judaism gets genuinely complex and genuinely honest. The question of why good people suffer, called *tzaddik v'ra lo* (a righteous person to whom bad things happen), is one the tradition has never stopped asking. Moses himself is said to have raised it with God, and the answer he received was not a neat explanation but something more like an encounter with mystery. The Book of Job is the most sustained and anguished engagement with this question in the Hebrew Bible, and it ends not with a satisfying resolution but with a confrontation with the sheer scale of creation. Job is not told why he suffered. He is shown something larger than the logic he came in with. Jewish thought has taken this seriously: it does not paper over the gap between what we expect and what we experience.

Later developments in Jewish mysticism, particularly in Kabbalah, introduced ideas that resonate more directly with what people mean by karma. The Kabbalistic concept of *gilgul neshamot*, the transmigration or reincarnation of souls, emerged as a way of making sense of apparent injustice. If a soul carries the moral weight of previous lives into a new one, then suffering that seems undeserved in this life might be understood as the continuation of an older story. This became influential in Lurianic Kabbalah, the school associated with Isaac Luria in sixteenth-century Safed, and it filtered into Hasidic teaching in later centuries. Not all Jewish thinkers accepted this, and mainstream rabbinic Judaism has often been cautious about it, but it shows that the tradition has more than one way of holding the question.

What Judaism insists on, across all its schools and centuries, is that moral action matters. The concept of *teshuvah*, usually translated as repentance but more literally meaning "return," captures this well. You are not locked into who you have been. The past has weight, yes, but it does not have the final word. You can turn, repair, do differently. This sits in some tension with a strictly karmic worldview, where consequences unfold with a kind of inevitability. Judaism wants to preserve both the seriousness of what we do and the radical possibility of change. The tradition holds these together without fully resolving the tension, which is part of what makes it so alive as a way of thinking.

If you are sitting with the question of whether your actions carry consequences, whether the moral texture of your choices actually means something, Judaism would say: yes, emphatically. But it would also say that you are not simply at the mercy of a cosmic ledger. You are in a relationship, with other people, with the world, and with something beyond you that cares about what you do and who you become. That relationship is not a mechanism. It is something more demanding and more generous than that.
