Is Astrology Kosher?

Is Astrology Kosher?


Predicting the future is big business. From newspaper astrologers to corporate consultants, there are many people out there ready to profit from our insatiable desire to know the unknown. Often, when contemplating major changes in my life, I am tempted to check my astrological reading. Is there anything wrong with this? Can an intelligent person believe in astrology without feeling ridiculous?

It is fascinating to note that the rabbis of the Talmud gave considerable credence to astrology. The Talmud states that “upon entry into the month of Adar one should become increasingly joyous. Rav Papa said: ‘Therefore a Jew should avoid litigation with gentiles in the month of Av, because his mazal is bad; and he should move the court case to the month of Adar, when his mazal is good.’”1 The Hebrew word which Talmud uses here, mazal, is usually translated “luck” but literally means “constellations.”

Astrology is not only a factor to be taken into account when planning future events—it also influences human nature. According to the Talmud, one born under the constellation of the sun will achieve eminence, and one born under Venus will become wealthy and immoral. One born under Mercury will be wise and have a retentive memory. One born under the Moon will suffer evil. One born under Saturn will suffer frustration, one born under Jupiter will be righteous, and one born under Mars will become either a surgeon or a slaughterer.2 A birthday is therefore viewed by the rabbis as a day on which personal astrological fortune is at its most potent.3

There is an uncomfortable contradiction inherent in all this. Although astrology is prominent in rabbinic thought, Jewish law cautions against seeking the advice of astrologers.4 But if astrology is a true science, why not consult it? The following Midrashic parable sheds light on this.

A king conquered a new province, the elite of which decided that they needed to forge connections with the new rulers. Some decided to become acquainted with the dukes, others with the knights and yet others with the ministers. The wisest amongst them declared, “I will forge a connection with the king himself.” He reasoned, “All the ministers, knights and dukes change; however, the king will always remain king.5

So, too, continues the Midrash, some people attribute power to the constellations and wish to serve them. Monotheistic believers, however, realize that G‑d is the supreme power, and that all other powers are no more than obedient servants who carry out His will.

Since everything in the universe is subject to the laws of cause and effect, according to nature the month of Adar is an astrologically lucky month, and a birthday has unique astrological potential for the celebrant. However, reliance on astrology could lead one to conclude that nature has a life of its own, and that the celestial spheres have powers independent of G‑d’s will. In fact, these are no more than a manifestation of the divine will. This is why prayer is so important. Mundane life seeks to convince us that life is dictated by the laws of nature. Prayer reminds us that nature is controlled by G‑d.

The message is clear: nature and its rules—including astrological truths—do exert an influence on our lives. It presents us with auspicious times and circumstances, and inauspicious ones; it imbues our character with certain traits and tendencies. However, one must recognize that ultimate power rests not with “nature” but with the Creator of heaven and earth.6

Talmud, Taanit 29a–b.
Talmud, Shabbat 156a. Although rabbinic consensus holds that Jews are not affected by mazal, the great medieval Talmudist Ritva (Rabbi Yom Tov ibn Asevilli, circa 1300) suggests that in this context the word mazal is to be understood as a generic term for “decree” rather than constellations. He thus suggests that when the rabbis of the Talmud say that Jews are not affected by mazal, they mean that they can subvert divine decrees through the performance of good deeds (Taanit 29a).
See Jerusalem Talmud, Rosh Hashanah 3:8, regarding the Amalekites: in their war against the Israelites they used soldiers who were celebrating their birthday that day, so that they would have an astrological advantage over the enemy.
Talmud, Pesachim 113b.
Midrash Rabbah, Eichah 3.
It must be noted, however, that not all the rabbis believed in the truth of astrology. In fact Judaism’s great codifier and philosopher, Maimonides (Rabbi Moses ben Maimon, 1135–1204), dismissed astrology as having no validity. See his Epistle to Yemen, Chapter 3, and his Commentary on the Mishnah, Avodah Zarah 4:7.
It should also be noted that none of this is intended as an endorsement of the modern-day “astrology” practiced by pop astrologers and published in Internet and newspaper “horoscopes,” which probably bear little or no relation to the ancient science of astrology mentioned in the Talmud.

Astrology is mechanical and works with formulas and for me it has been very seductive, yet as much as I wanted it to be a guide, it brought the spirit of confusion into my life. It is ancient and originally for agriculture, planting and seasonal rituals. The zodiac signs are beautiful mythic map and their sequence is a model of the cycle of life and civilization. In the end, the signs are like the color wheel, but it takes an artist to paint a picture. Astrology has been a great temptation in my life, and I have learned enough to construct charts but afterwards I felt like a voyeur. What is luck? what is bad Luck? Who am I to say? I would rather think of blessings. I will stick with the beautiful moon and suns. That's all I can handle and I don't need a horoscope to see their influences. Reply

I thought the most common Jewish consensus is that astrology and the like don't have meaning for us.

Jeremiah 10:2 So says the Lord: of the way of the nations you shall not learn, and from the signs of the heaven be not dismayed, for the nations are dismayed from them.

which is quoted approvingly in gemara (Shabbat 156a):
Rabbi Yoĥanan said: There is no constellation for the Jewish people that influences them. The Jewish people are not subject to the influence of astrology. And Rabbi Yoĥanan follows his own reasoning, as Rabbi Yoĥanan said: From where is it derived that there is no constellation for the Jewish people? As it is stated: “Thus said the Lord: Learn not the way of the nations, and be not dismayed at the signs of heaven; for the nations are dismayed at them” (Yirmiyahu 10:2). The nations will be dismayed by them, but not the Jewish people. Reply

As a young child I had an interest in the stars. While looking for cartoons in the newspaper I saw the daily horoscope and asked my Mother about it. Her knowledge was limited so she took out a library book on the subject for children. It explained about the different signs, what a horoscope was and about how ancients used astrology for prediction.
After reading this book I found that my understanding of the subject went beyond what was in there. I felt that this was a tool given to me.. I learned about myself which has helped me throughout life. Personally I feel there is no harm as long as astrology is not used for prediction or to see if it is your "lucky day". My belief in G-d is unquestionable. My knowledge of astrology gave me the information I needed to know where my interests music, dance, theater. I don't think it did any harm and over the years my talents have brought much joy and happiness to others. , That was G-d's "gift" to me. Reply

The 'Sefer Yetzirah' (Book of Creation),whose authorship is attributed to our Patriarch Abraham, is probably the first Kabbalistic text to address itself to the signs of the Zodiac'. But, is a Jew's destiny, or 'Mazel' (luck) locked into the stars? Our Sages, emphatically, say No; (B.Tractates, Shabbos,156b; Nedarim 32a). Turning to Scripture; Exodus,10:10, & Rashi's comment, Pharaoh says: my astrological calculations show that the
star 'Raah' (Evil), a sign of blood and, killing is rising towards you in the desert". Following the sin of the golden calf, G-D did wish to destroy the Israelites, (Exodos, 32:10); but, after Moses' prayers, G-D reconsidered,and the 'Evil' turned into the blood of circumcision, Joshua,5:3. A scriptural example that a Jew's 'mazel' is not bound by the constellations. Reply

Ha-Shem created the stars and planets, and a system of governing influence on high through that celestial means, according to the RaMChaL in Derech Hashem. All the nations had a celestial "governor" above each nation in that system of things, Egypt having the most powerful governor according to tradition.

To worship their "governors", the ancient nations commited idolatry and blasphemy, and Israel was commanded to worship only Ha-Shem who created everything above and below including that celestial system of governance.

Israel was excluded from that system when they accepted to receive the Torah, and they can bypass that whole system through the Torah and G-d's names. As every Jew knows, Eretz Israel, the Torah, Ha-Shem and His people are one. Reply

We make our own luck and it is wrong to try to get luck on our side by choosing the most opportune time or circumstances.

The belief in an external cause of luck is like taking away part of the Divine atributes and allowing them to go into material concepts where they do not belong. At this rate we will soon be saying our prayers to the sun amd moon! Reply

I'm pleased to see this article. I've been reading responsa by the Rambam on this subject. Of course I have the highest respect for the Rambam AND the world was still 'flat' in those days. Then, just as now, there are charlatans who do a disservice to astrology and its use. My sense is that the Rabbis were more interested in protecting the community from those who would prey upon them when they dismissed astrology.

Using astrology for psychological insight, based on achetypes associated with planets, is invaluable. Most serious astrologers know that predictions are risky business. Understanding ones inner workings, in relationship to Hashem and other people, only serves to raise consciousness. A higher consciousness only increases the sense of awe. The planets aren't deities, they are another mysterious creation of the One G-d.

Hashen created the heavens and the earth. Reply

People need to understand the different practices of astrology.
There is Horoary, which attempts to determine future events. This is what Pharaoh used, and it is vague, and though effective, is the practice forbidden to Jews, and people are apt to fail like Pharaoh.
Natal astrology is the practice of determining one's personality and characteristics from the alignment of planets, and their placements in the signs at the moment one is born. This is perfectly permissible, and the Vilna Gaon says one must study the Mazal of one's children in order to know how to raise them properly in their way. One can learn volumes about oneself, and channel their energies in serving G-d, through ones knowledge of oneself, through ones personality that is determined by G-d through the stars and planets at one's birth.

I want to know if the signs of the zodiac are meant to be good or bad?
They are drawn on the temple walls, right?
Why were they allowed?
Did the meaning change over the years? Reply

We as with our ego, would think we have free will. Just like billiard balls on the table, we see other balls moving, but we cannot see the big picture. We think we have free will.

But Divine intelligence sees a macroscopic view, and knows where the balls are headed, but we do not. They know where our destiny lies.

But does that elude us from working and striving hard, absolutely not. We need to keep working hard and strive, as a ball can change its direction if we work hard enough. We would still need to work hard to progress and prosper, albeit not entirely knowing where our destiny lies.

Astrology is a natural physics of the universe. But Divine intelligence is free of all laws. It can superced it. We of course can pay attention when to sow, when to reap, but did not God allow Moses to defy natural laws and part the Reed sea?

Therefore pay attention to the natural laws, but work hard in your own field, and supplicate to Him. Reply

Stargazers' predictions are very vague and indefinite.The statements thay make are so broad in their meaning that we can interpret them in hundreds of different ways.
Possibly it has some parallels with poetic verse - the feelings of one person can be similar, to a certain degree, to those of another one.
So I believe that horoscopes are not woth paying attention to, for the astrologers speculate on other peoples problems and difficulties. Reply

This midrash and the comment of 10-28 reminds me of finding my sobriety after years seeking external means of spiritual enlightenment. Twelve Step programs suggest willingness to "go to any lengths," knowing that when we turn our individual wills over to HaShem ( our Jewish Higher Power), the any length was within us all along. We learn to use spiritual tools, but the G-d is the Great Architect. Reply

I have for many years considered an individual living entity (as in you, I or a rabbit that runs into a rock) as being "eddies in the electromagnetic field of the Earth" I will add that "living" entities do attain some form of volition or will and it is this consciousness of will that could be construed as the self deterministic ground of all being.

Being that the Earth is a self deterministic field within the quantum soup of the universe/multiverse and that quanta are an effect of this electromagnetic soup, what is to say that other "gross" fields of self deterministic quantum entities do not have some effect and relevence to and on conscious beings within these quantum fields?

Quantum dynamics has shown that each and every quantim field string packet brane knows where each and every other quantum field string packet brane in the entirety of " " is, where it is going, where it has been, how fast it is travelling and in which direction it is rotating in relationship to itself.

I dont believe in astrology at all..Infact I think that the Rabbis shudve put restrictive fences around the law that prohibits worhsipping stars and all that...I consider astrology close to idol worship..The Torah clearly says not to believe in it..How can the rabbis of the Talmud give such advice that in Adar their luck is good and sometimes its bad..

G-D controls everything...No star or constellation can affect anybody if G-D doesnt wishes. Reply

Rabbi I have a story relating to your Shiur. A great man was speaking to a friend that was out of luok always looking into the future and never getting his way. So this great man told him to go with him up a mountain to find gold at the top where he was sure there would be. his friend was overwhelmed with the thought and couldnt wait to go . on the way up the great man stops and says here we are . his friend responds we have not found the gold. the great man responds saying that the gold is you .all that you were looking forward to climbing the mountain and believing that the gold would be at the top brought you to a high instead of taking each step knowing you are making the effort whether you find the gold or not. all decisions should be made with a comfortable understaning that you will always be the gold to you and to me. have a shavua tov and thank you for reading.

It's written somewhere that a gentile can't change his "mazal" -his luck or destiny. But a Jew has the power to do this through prayer. Perhaps astrology is there to help usd understand what we need to pray for? I also find the idea paganistic--althought I used to think the idea of animal sacrifices in the Holy Temple was pagan too until I learned more about it. There are many things in Gd's amazing universe that we don't completely understand, like how something can act like a particle and a wave? How can the position of the planets affect what will happen to a person in their life? Same idea. Basically I think that it's better not to worry about it and just pray for what we want from life.

I am a frum (religious) Astrologist. It seems that your article and most people automatically equate Astrology with future-predicting. However, these days (the 20th century) most Astrology is psychology oriented. Meaning that it allows people to understand the subconscious influences from environment, family, career that create and motivate an individual's personality. Today Astrology is about understanding the individual to help overcome obstacles that might not be clear on the surface.
Future-predicting is still out there but it is extremely difficult even for veterans of Astrology and even then it is vague.
But using Astrology to help understand oneself can help a person to find themself spiritually as well as becoming stronger all around. Reply

Abraham was very saddened because he could not have children. G-d saw his sorrow and asked him what made him so sad. Abraham answers that the Chaldeens, who know the science of stars, confirmed him that he would not have any descendance. Then G-d answers that since He Created the stars of the universe as well, no planet was going to resist G-d's Will, and that despite what the Chaldeens had predicted, Abraham would have a descendance. Astrology IS indeed for REAL: however by chosing G-d's path (Torah & Misvos), one can ALWAYS change a negative decree. This is how it works. Reply
