Many people are convinced that reincarnation, called gilgul in Hebrew, has been accepted as a fact since ancient times. Reincarnation is the belief that when people die they are transported into a new body in another life. This is not true about Judaism. Gilgul entered Judaism for some mystical-minded Jews only in the Middle Ages.
I will summarize some scholarly ideas about the Jewish view and follow them with my ideas.
In her 2001 Ph.D. Thesis, “The Soul and Afterlife in Jewish Mysticism and Gnosticism,” Dr. Dina Ripsman Eylon gives us the origin of the notion of reincarnation in Judaism. It is available on Academia.edu.
Among much else, she informs us that the twelfth-century kabbalistic work Sefer Bahir, which means “Book of Clarity,” is the first book that introduces the theory of reincarnation as a Jewish theological theory. It is an anonymous mystical work attributed to a 1st-century rabbinic sage Nehunya ben HaKanah because it begins with the words, “Rabbi Nehunya ben HaKanah said.” It is also known as the Midrash of Rabbi Nehunya ben HaKanah.
The book explains the mystical significance of many items. These include biblical verses, the shapes of the Hebrew letters, the biblical cantillation signs and vowel points added to the letters, the earlier mystic book Sefer Yetzirah, the use of sacred names in magic, and it introduces the idea of reincarnation.
Gershom Scholem, the renowned scholar of Jewish mysticism, dated Bahir’s composition to 1176 and said the book enormously impacted Jewish thought. But not every scholar agrees with his dating of Bahir. Some date it later. Some assert that the doctrine of reincarnation was not in the original version of Bahir. They claim that different publishers changed and added to the original, even frequently. What is certain is that while other religions and cultures may have accepted the notion of reincarnation as a fact, Judaism did so only when it was introduced in Bahir. There is no hint of it in the Torah, Talmuds, and early Midrashim.
Rational thinking Jews rejected the idea that humans lived former lives. Mystical thinkers such as the Greek Plato (circa 428-347 BCE) and the Jewish Nachmanides (1194-1270) accepted it. However, the Greek Aristotle (384-322 BCE) and the Jewish Maimonides (1138-1204) rebuffed the idea.
Dr. Eylon recognizes that Jews may have taken the concept of reincarnation from non-Jews. She adds that some Jews were able to accept the notion because they had already adopted that souls exist, a belief that is also not in the Hebrew Bible. Philo (25 BCE-50 CE) was the first Jewish philosopher to introduce the idea that there is such a thing as a soul that exists separate from the body. It contains the intellect and personality of a person. Platonic theories influenced him. He considered the soul to be eternal. However, he did not have the belief in reincarnation. The soul remained somewhere in limbo until the messianic age when it would be revived.
Neither Aristotle nor Maimonides decided that there is a soul. Aristotle wrote that the intellect was part of the body. Nothing on earth disappears. It is often transformed into something else. The body is transformed and absorbed into the world, but the intellect goes elsewhere. Maimonides agreed with him.
Why did many people accept that reincarnation happens?
We do not know. However, most likely, it is caused by the imperfections in human beings.
Most people know little about their religion. Those who know something only remember what they learned in a Sunday School or several afternoon churches or synagogues a few hours a week. These lessons were what children could absorb, not the truth adults should know.
Many learned about their religion by listening to the radio or TV preacher who was more interested in their money than in their education or to rabbis who taught interesting but untrue homiletical Midrashim in their sermons as facts.
Others saw a bearded, saintly-looking man saying what he claimed was wisdom and believed it because of his beard or piety.
Still others accepted teachings that were not rational, such as, “You need to take a leap of faith,” and took no time to translate it as “If you find a religious thought to be illogical, you should accept it anyway.”
Or they swallowed the belief that people are reincarnated from one body to another and never die because it makes them, like many other people who dislike or fear the thought that there is no life after death, feel better. They will exist even after they die, albeit in a different body, without recollecting the past.
Additionally, reincarnation is a convenient explanation of why righteous people suffer. They are punished for misdeeds they committed in a prior life. It also explains why many evil people prosper. They are rewarded for the good they did in a former life.
So, for many rational people, reincarnation is untrue.

The Zohar says: “All souls are subject to the trials of transmigration; and men do not know the designs of the Most High with regard to them… The souls must re-enter the absolute substance whence they have emerged.”
“Every soul… comes into this world strengthened by the victories or weakened by the defeats of its previous life” (Origen, De Principiis).
“The disciples of Jesus were persuaded that a man might have sinned before he was born, (John, ix. 2,) and the Pharisees held the transmigration [reincarnation] of virtuous souls, (Joseph. de Bell. Judaico, l. ii. c. 7;) and a modern Rabbi is modestly assured, that Hermes, Pythagoras, Plato, etc., derived their metaphysics from his illustrious countrymen” (Edward Gibbon; Decline & Fall 1590)
Philo says that the air is full of spirits, and that some, through their natural propensity, join themselves to bodies; and that others have an aversion from such a union.
Josephus says in relation to the Essenes that they “…resigned up their souls with great alacrity, as expecting to receive them again. For their doctrine is this, that bodies are corruptible, and that the matter they are made of is not permanent; but that the souls are immortal, and continue for ever; and that they came out of the most subtle air, and are united to their bodies as to prisons, into which they are drawn by a certain natural enticement; but that when they are set free from the bonds of flesh, they then, as released from a long bondage, rejoice and mount upward…”.
St. Jerome wrote: “The doctrine of transmigration (reincarnation) has been secretly taught from ancient times to small numbers of people, as a traditional truth which was not to be divulged.”
What do you think of these quotes and Josephus?
The Zohar is filled with fanciful notions that I do not believe. I do not believe in reincarnarnation even though the Zohar does and many Jews as well. Nor do I think God is made up of ten part which came apart and humans need to help but God together again, as the Zohar claims. I wrote an essay showing that the Zohar is a forgery.
We agree with Saadiah Gaon on the subject of reincarnation. It is not logical.
I agree with you and Saadiah Gaon. I also do not believe in reincarnation. I read your essay proving that the Zohar is a pious forgery. I liked it, and I agree with it. I also think the Zohar is a forgery.
Thanks.
In his book Nishmath Hayem, Rabbi Manasseh ben Israel (1604-1657) wrote: ”The belief or the doctrine of the transmigration of souls is a firm and infallible teaching accepted by the whole assemblage of our people with one accord, so that there is none to be found who would dare to deny it… Indeed, there are a great number of sages in Israel who hold firm to this doctrine so that they made it a teaching, a fundamental point of our religion. We are therefore in duty bound to obey and to accept this teaching with acclamation… as the truth of it has been incontestably demonstrated by the Zohar, and all books of the Kabalists.”
But I agree with the Saadia Gaon that reincarnation is nonsense. The Saadia Gaon explains:
“Yet, I must say that I have found certain people, who call themselves Jews, professing the doctrine of metempsychosis (reincarnation) which is designated by them as the theory of “transmigration” of souls… Many of them would go so far as to assert that the spirit of a human being might enter into the body of a beast or that of a beast into the body of a human being, and other such nonsense and stupidities… This in itself, however, indicates how very foolish they are… such reasoning is a deviation from logic. [They argue]: “Inasmuch as the Creator is just, it is inconceivable that he should occasion suffering to little children, unless it be for sins committed by their souls during the time that they were lodged in their former bodies.” This view is, however, subject to numerous refutations. The first is that they have forgotten what we have mentioned on the subject of compensation in the hereafter for misfortunes experienced in this world…. They return to our theory and are forced to give up their insistence on the view that man’s suffering in this world is due solely to his conduct in a previous existence.” Saadia Gaon, “The Book of Beliefs and Opinions”
Reincarnation says that when good people suffer it is because of their sins from a prior life. That’s a horrible concept! Does that mean that every person who died tragically deserved it? Plus, that would mean that we should treat those people poorly because they must have done something wrong in a prior life. That’s a dangerous mindset to have.
If reincarnation were true it would mean that there’s no such thing as random chance. If someone were genuinely a good person then nothing should ever happen to them. They could just walk right through a war zone and never die because they’re not evil enough. But where is this person who is impervious to all evils?
I agree. I do not think reincarnation occurs. There is no proof for it nor any rational reason why it should occur. It is wishful thinking on the part of some believers. However, I joke that I must have been a wonderful person in my prior life for God to reward me with a gem of a wife like Dina.
Also its very irrational to assume bad thigns occur because of reincaranation
A bear doesn’t attack you because you “were” a bad person in the past.
They attack you because they are bears.
A flower doesn’t hit you because you dropped a lit a fire on shabbath.
A flower hits you because of the wind.
We agree.
I think reincarnation is a lie, it is untrue. We cannot recall past lives.
We agree.
Yes. Resurrection (principle of Judaism) and reincarnation (foreign to Judaism) are very different concepts.
Yes, it is also a fact that no one is perfect.
Dear Rabbi Isreal Drazin ! The concept of resurrection is referenced in the Torah in several ways. According to Pesachim 68, it is mentioned when God says, “I put to death and I make live,” and it continues, “I have wounded, and I will heal.” This is interpreted as God having the power to give life to those who previously died and heal those who were wounded. In Sanhedrin 92, the scripture, “And many of those who sleep in the dusty earth shall be awaken; these for everlasting life, and these for shame…” is provided as a source for the resurrection of the dead. It also mentions the prophet Ezekiel resurrecting the dead, however there are multiple interpretations of this event. Lastly, in Sanhedrin 90, Rabban Gamliel provided the source for the Resurrection of the Dead in the Torah being God saying to Moses, “Behold, you will lie with your forefathers and rise…” These references suggest the belief in an afterlife and the resurrection of the deceased. The Ph.D. Thesis, “The Soul and Afterlife in Jewish Mysticism and Gnosticism,” of Dr. Dina Ripsman Eylon is surely a great academic achievement and for many people (rational or not rational), the principle of resurrection is untrue, which influences their decision for a certain burial practice (e.g. cremation).
I agree with you entirely. I personally believe that reincarnation doesn’t exist. Personally, I find the thought appalling. I don’t want to be a snake. I cannot imagine anything more horrifying than hopping about from snake to wasp to tree. It is mystical, and not rational.
Genetics, disease, drugs, and diet can all effect an embryo, and are scientifically proven. Reincarnation is not proven. Why imagine a reason, when science provides an explanation?
Furthermore, there is no evidence for reincarnation. And the view that a person receives what he gives to others is not true. There were many great people, some who lived to old age and some who died young. That refutes karma, and reincarnation has never been validated. There’s no evidence.
Maimonides would not have believed in reincarnation. Aristotle rebuffed metempsychosis, writing, “as if it were possible for any chance soul to enter into any chance body”. Thus, I do not believe in reincarnation.
We agree.
Resurrection and teincarnation are not identical. The former means a person’s body and soul are rejoined after death, which is a principle of Judaism,. Though you think Maimonides was a hypocrite, that’s what the Talmud says. Reincarnation or the migration of souls refers to a person’s soul finding a different ‘host’ after death. Rav Saadiah Gaon discusses the latter and says it is foreign to Judaism. Sefer Bahir is accepted to contain elements dating to tenth century Babylonia.
Thank you for pointing out my mistake Shmuel. You are certainly correct.The technical definition for reincarnation is the revival of life after death. In contrast, reincarnation, refers to the migration of a person’s soul to a diffent body after death. I should have used the word reincarnation, not resurrection. I wish I were perfect, but I am not. I especially appologize to Dr. Eylon who used the correct term throughout her excellent and interesting Ph.D. Thesis.
