What is reincarnation?

Within Judaism, the concept of reincarnation is known as *gilgul* or *gilgul neshamot*, which translates roughly as the "rolling" or "cycling" of souls. It is not a universally held belief across all Jewish traditions, but it became a significant and deeply developed idea within Kabbalah, Jewish mysticism, particularly from the medieval period onwards. The Kabbalists understood the soul as something that might need more than one lifetime to fulfil its purpose, repair what was broken, or complete what was left undone. This is not quite the same as reincarnation in Eastern religious thought. The Jewish version is less about an endless wheel of rebirth and more about a purposeful, directed journey toward wholeness.

The most detailed and influential treatment of gilgul comes from the Lurianic Kabbalah, the school of mystical thought centred on Rabbi Isaac Luria, who lived in sixteenth-century Safed. Luria and his circle, particularly his student Rabbi Chaim Vital, developed an elaborate understanding of how souls move through different lifetimes. They connected this to the concept of *tikkun*, which means repair or rectification. The soul, in their view, carries unfinished spiritual work from one life into the next. A person might be born into particular circumstances, or encounter specific people or challenges, precisely because the soul needs those conditions to complete something it could not complete before. This gives the struggles of an individual life a kind of cosmic weight and meaning.

It is worth knowing that gilgul is not mentioned explicitly in the Torah or the Talmud. This absence is part of why some Jewish thinkers, particularly rationalist philosophers in the medieval tradition, were sceptical or openly dismissive of the idea. Saadia Gaon, writing in the tenth century, argued firmly against it. Maimonides, the towering rationalist figure, made no place for it in his understanding of Jewish theology. So if you come from a more philosophically oriented or non-mystical strand of Judaism, you may find that gilgul sits at the edges rather than the centre of your tradition. It belongs more comfortably in Hasidic and Kabbalistic communities, where it became part of everyday spiritual language.

For those who do hold it, gilgul can offer something genuinely consoling and also quietly demanding. It is consoling because it suggests that a life cut short, or a life full of suffering that seems disproportionate or senseless, is not simply a random accident. There may be something the soul is working through, something larger than what fits into a single span of years. It is demanding because it places real weight on how you live. If your soul is here to repair something specific, then the choices you make, the relationships you tend or damage, the ethical and spiritual habits you build or neglect, all of this matters in a deep and continuing way. Nothing is wasted, and nothing is without consequence.

If you find yourself drawn to this idea, it is worth sitting with the fact that Jewish tradition holds it lightly in some ways even while taking it seriously in others. It was never made into a binding article of faith in the way some doctrines are. That leaves space for you to engage with it honestly, whether as a framework that brings meaning to your experience, as a poetic way of understanding human connection and recurring patterns in your life, or simply as one thread in a much larger and richer conversation about what the soul is and where it is going. The Kabbalists would say the very fact that a question like this stirs something in you is not accidental.
