The Life of the Soul is
a rich and meticulously researched volume that explores the development of
Jewish conceptions related to reincarnation (gilgul neshamot) from
medieval Kabbalah to Hasidic thought. Edited by Andrea Gondos and Leore
Sachs-Shmueli, the book brings together contributions from leading scholars — including
Moshe Idel, James A. Diamond, Ariel Evan Mayse, and Shaul Magid — as well as
emerging researchers, offering a comprehensive examination of how Jewish
mystics grappled with the idea of the transmigration of souls.
It’s always difficult to review
edited volumes because each contribution has its own voice, its own
methodology, and its own point. The different contributions usually focus on a
specific kabbalist or kabbalistic text’s view on the topic of reincarnation. Rather
than focusing on individual essays, this review highlights the overarching
themes that unify the volume. The contributors trace the evolution of
reincarnation doctrines across key Kabbalistic texts, from the Bahir and Zohar to
the works of Nachmanides and his disciples, later Lurianic Kabbalah, and
Hasidic homilies. A recurring methodological strength is the careful mapping of
how ideas were transmitted, adapted, and reinterpreted across generations,
often with subtle but significant variations in terminology. In doing so, the
scholars carefully trace the first instances of each idea discussed and then
often mapping out the genealogy of how various kabbalistic sources were
influenced by each other’s novelties.
One central discussion revolves
around the relationship between gilgul (transmigration)
and sod ha’ibbur (the "secret of impregnation"), two
concepts frequently conflated in Kabbalistic literature. The book distinguishes
between horizontal reincarnation (movement between beings on
the same ontological level, such as human to human) and vertical
reincarnation (movement up or down the chain of being, from human to
animal or even plant). The latter notion, eerily resonant with modern
scientific ideas like the conservation of mass, underscores the Kabbalistic
view of a dynamic, interconnected cosmos.
Several essays explore the
intersection of reincarnation with halakhic (Jewish legal) discourse. One
striking example is the link between gilgul and the
commandment of procreation: some sources frame reincarnation as a mechanism for
allowing the souls of those who died childless to have another opportunity to
fulfill this special mitzvah. This is sometimes viewed as a way to
“punish” those who failed issue offspring, while others see it in a more
positive light as a means of giving a person a second chance to achieve in
another lifetime what he failed to achieve in a prior lifetime. Similarly,
esoteric interpretations of yibbum (levirate marriage) suggest
that the deceased brother’s soul may reincarnate in the child born to his
widow. Even the laws of shechitah (ritual slaughter) are
imbued with mystical significance, as some Kabbalists viewed the act as a means
of elevating the animal’s soul. An idea especially expanded upon in Hasidic treatments
of gilgul focuses on how gilgul enables a person to fulfill more commandments
than one was able to fulfill in a single lifetime.
The volume also delves into the
Zoharic portrayal of reincarnation — particularly in Saba d’Mishpatim —
where unfavorable incarnation cycles are likened to enslavement, drawing a
provocative parallel to the Torah’s laws concerning Hebrew bondsmen and
slavegirl. The cyclic nature of gilgul (literally
"wheel") aligns with broader Kabbalistic conceptions of time,
including the monthly lunar renewal, seven-year shemittah cycles,
and 50,000-year Jubilee cycles (shemitta hagadol). When coupled with the
idea of reincarnation, this cyclic view of history can be quite inspiring in
times of oppression, as it gives hope to the Jewish People that even if things
are not going well right now, there will eventually be a positive upswing in
the cycle.
Comparisons with Eastern
religions, particularly the concept of karma, are briefly addressed in several
essays, though the focus remains on Judaism’s unique theological concerns. Some
essays touch on how Biblical and Rabbinic figures were retroactively
interpreted as reincarnations, such as Abraham bring linked to Adam; Terach, to
Job; Moses, to Abel; and Jethro, to Cain. As part of the genre, there is also a
discussion of Nebuchadnezzar’s metamorphosis into an animal as foretold by
Daniel.
An adjacent topic treated in this
book is known popular parlance as an ibbur or dybbuk. Those terms
refer to the phenomenon of a living person’s body being possessed by the soul
of the dead. In some ways, this is also a type of reincarnation. One chapter is
devoted to discussion of how rabbinic exorcists would help remedy those people
whose bodies had been possessed, specifically focusing on episodes from the
personal memoirs of two such mystics, Rabbi Hillel Bbaal Shem (17–18th
century) and Rabbi Yehuda Fetayah (19-20th century). These rabbis
are presented as shamans who used their knowledge to not only chase away
demonic or dead forces from the bodies of their victims, but even to use those
episodes of possession to their advantage to gain more knowledge of the
spiritual underpinnings of the soul’s movements.
The kabbalistic sources treated
discuss also questions like: How many times can a single soul be reincarnated?
Can a soul change species (from person to animal or even mineral, or vice
versa) or gender (male to female, or vice versa)? How does the concept of gilgul
jibe with earlier Jewish beliefs about resurrection of the dead (techiyat hameitim)?
Into which of a given soul’s multiple bodies will a soul be reincarnated in the
End of Days? With which spouse will one enter eternal rapture? Can a Jewish be
reincarnated as a non-Jew or vice versa? Fascinatingly, Rabbi Levi Yitzchok of
Berdechiv presents three answers to the first question: either one returns in
their first body (Kabbalists), their most recent body (philosophers), or the
soul is embodied by the limbs that had been repaired through fulfilling mitzvot
whatever incarnation that limb was rectified (his preferred answer) without
favoring one entire body over another.
Additionally, this volume does
not shy away from the philosophical tensions raised by reincarnation. How
does gilgul align with the doctrine of bodily resurrection (techiyat
ha-meitim)? Can a soul change gender or species between lifetimes? How does
reward and punishment function if deeds from past lives influence one’s current
fate?
Some of the difficult questions
about gilgul led Jewish philosophers who are less
kabbalistically-inclined to outright reject the notion of reincarnation as a
non-Jewish belief. Rabbi Saadia Gaon was famously the first Jewish philosopher
to do so, as did Rabbi Jedaiah HaPenini Bedersi. Maimonides was reticent on the
topic of reincarnation and scholars have speculated that he too rejected the
idea. Yet other Jewish philosophers like Rabbi Chisdai Crescas and his student
Rabbi Yosef Albo see the doctrine of reincarnation as incompatible with their
understanding of Jewish philosophy and how the soul works, but nonetheless
ultimately did not reject it simply because it had already become a
well-accepted tradition that was understood to have come down through legitimate
tradents. The final three chapters focus on how Hassidic masters invoked the
concept of gilgulim in their sermons to add an esoteric dimension to offer hope
and inspiration to ordinary Jews.
The editors and contributors
deserve praise for balancing scholarly rigor with accessibility, making this
volume invaluable for academics and interested lay readers alike. The endnotes
to each essay are full of references to relevant primary and academic sources
on the topics discussed (and sometimes tangential comments as well). Obviously,
as with any scholarly work on kabbalah the specter of Gershon Scholem looms
large in the endnotes, whether one agrees with him or disagrees with him. With such
erudite scholarship, The Life of the Soul is a landmark
contribution and resource to the study of Jewish mysticism. It not only charts
the historical development of reincarnation theology, but also illuminates its
enduring spiritual and existential power.
