For me, joining Judaism wasn’t about God or spirituality, but it was about becoming a better person and a better member of my community (both within my Temple and in the world at large). What drew me in was Jewish practice, especially in Reform Judaism, which is focused on self-reflection, repairing the world, helping others, and expressing gratitude.
Discovering Mussar
During the period of taking classes on my road to conversion, I was genuinely delighted to discover Mussar. It immediately felt familiar – almost like the Jewish version of Groundhog Day (which I wrote about here), where the work is to keep noticing your flaws, try again, fail better, and slowly become someone worth being. I’m not part of a Mussar group, and I’m not doing the full Mussar program, but simply learning about it felt like finding a framework that fits my aspirations really well. Phil Connors becomes who he’s meant to be not through enlightenment, but through repetition, accountability, and daily ethical effort – which is about as Mussar as a Hollywood movie gets.
Mussar is the Jewish practice of intentionally cultivating and balancing your character traits so you can live more ethically, compassionately, and responsibly in the world.
Where Mussar Comes From
Its roots go back at least a thousand years to medieval Jewish thinkers like Bahya ibn Paquda and Maimonides, who wrote entire books about shaping your inner life – humility, patience, gratitude, anger, honesty, discipline. They argued that holiness isn’t about mystical experience but about getting your traits into balance. Over the next several centuries, Jewish writers produced a whole bookshelf of ethical guides that read like proto-Mussar manuals: daily self-examination, small behavioral changes, cultivating virtues, avoiding extremes. It’s surprisingly close to what we now call CBT or habit-building, just written in the language of the Middle Ages.
The Mussar we know today really took shape in the 1800s, when Rabbi Israel Salanter created a full-blown movement in Lithuania devoted to character formation. He turned these ancient ideas into a practical system – studying one middah at a time, journaling, chanting phrases to internalize virtues, holding each other accountable, and paying close attention to how we actually behave in the world.
Mussar was centered in the great Lithuanian yeshivot and small-town study circles of Eastern Europe. When the Holocaust destroyed those communities, it destroyed the entire ecosystem that carried Mussar forward: the teachers, the students, the institutions, and the culture of daily ethical practice that Rabbi Israel Salanter had built over three generations.
A few Mussar texts survived, but the living tradition – the mentorship, the drills, the small-group accountability, the way Mussar was woven into everyday life – was devastated. After the war, Judaism’s immediate priorities were survival and rebuilding, not reviving a character-development movement that required time, stability, and intimate community life. Mussar continued quietly in a handful of Orthodox yeshivot, but it wasn’t widely known outside those enclaves.
That’s why the revival in the 2000s feels so striking: a practice that was nearly extinguished found new soil in American Jewish life, where people were suddenly ready for exactly what Mussar had always offered – a structured, communal way to work on becoming better human beings.
Mussar found new life in the early 2000s when Jews outside the Orthodox world began rediscovering it as a practical, community-minded approach to character rather than belief. A major catalyst was Alan Morinis, whose writing and teaching reintroduced Mussar to Reform and Conservative synagogues, creating study circles, courses, and a renewed movement that brought this nearly lost tradition back into everyday Jewish practice.
Middot in Real Life
The middot (plural for middah) are the individual character traits – patience, humility, generosity, courage, truthfulness, gratitude, trust, compassion, etc. – that Mussar treats as adjustable qualities we can refine and bring into balance.
In modern psychology, we talk about the Big Five personality traits. I’ve taken the test: very conscientious (80th percentile), pretty prone to anger (67th percentile), and low on humility (14th percentile). In other words: I like things done right, I get irritated when they’re not, and I’m overly convinced that my version of “right” is correct..
Judaism has its own vocabulary for this. None of these traits are good or bad on their own. Each one is a slider.
Too much humility and you become a doormat. Too little and you become insufferable. Too much anger and you scorch the earth. Too little and you never stand up to anything. The Jewish insight is not “become a different person,” but: adjust the dials so your traits actually serve the good rather than just serving your ego.
Mussar, as a discipline, is simply the practice of paying attention to those sliders and doing the slow work of moving them. That ongoing rebalancing – in relationship to other people and to the world – is what “holiness” looks like in practice.
On the surface, Mussar looks like a self-help program: pick a trait, notice how it shows up, try small experiments to change your behavior. Rinse, repeat. There are journaling exercises. There are little practices. There is a lot of “try again tomorrow.”
But the crucial difference is this: in Judaism, you’re not working on your character just so you can be calmer, or more “optimized,” or more successful at work. You’re working on your character because other people have to live with you.
One Mussar teacher puts it bluntly: it is “working on yourself – but not for the sake of yourself.” That’s what I want. The point of becoming more patient, more humble, more generous is not so I can feel serene. It’s so my wife doesn’t end up on the receiving end of my impatience. It’s so my community is kinder, fairer, more honest. It’s so the world – in whatever tiny corner I touch – is less of a mess.
Self-help often stops at “How can I feel better?” Mussar keeps asking, “How can I treat people better?”
Judaism even builds an annual reset for this work into the calendar – a rhythm of reflection, intention, forgiveness, and fresh starts. (I’ll write about that separately, but – yeah - it's the High Holy Days)
One of the most useful things Mussar has reinforced within me is the idea that every trait has a light side and a shadow side, and you don’t get one without the other.
My anger, at its worst, is reactivity and impatience. At its best, it’s clarity and the willingness to say “this is wrong.” My stubbornness makes me hard to live with; it also means I don’t give up on people easily. My drive for order makes me rigid; it also makes me reliable.
Judaism is very comfortable with this both/and view of human beings. You don’t exorcise your bad traits and keep only the good ones. You recognize that they’re two faces of the same thing and then you work at steering the energy in better directions. That feels much more realistic than the fantasy of becoming a completely transformed person.
Another way Mussar goes beyond self-help: its scope is bigger. The goal isn’t just to be kinder to the people you love or more civil in your little group. Jewish practice pushes outward: you’re supposed to extend that work even toward the people you dislike, disagree with, or consider your enemies.
If your patience and humility stop at your own social circle, Judaism would say you’ve missed the point. The aim is to help build a moral and ethical society for everyone, rooted in justice and compassion – shalom in the fullest sense: wholeness and peace for the world, not just inner calm for you.
None of this is quick. Mussar is not a makeover. It is the long, slow practice of noticing who you are in real time and making slightly better choices, over and over, in the direction of decency.
For some people, self-improvement means buying a new planner or downloading a meditation app. For me, it means looking at my middot, admitting where they’re out of whack, and using this old Jewish toolkit to nudge them toward balance – for my sake, yes, but even more for everyone who has to share a life, a community, or a planet with me.
Or, to put it another way: Mussar is Judaism’s Groundhog Day. You wake up, see what you messed up yesterday, and try to do it a little better today. No perfection. Just practice.
In other words: Judaism, through Mussar and middot, has become my way of being a little less of a jerk and a little more of a mensch. The rest is just practice.
