Jewish astrology: mazal, zodiac and choice

Study Jewish astrology in four steps: define mazal, read a Sefer Yetzirah zodiac correspondence, compare named positions and create a useful source note.

Start this path

Begin with the words and relationships that make Jewish astrology interesting: mazal, zodiac signs, Hebrew months and letters. You will read an actual correspondence, follow a disagreement and turn a symbolic theme into a small learning exercise.

The destination is a source note you can explain to someone else. Keep the text’s claims, your interpretation and your own choices visible as you work. Short readings are enough to begin; no Hebrew knowledge or birth details are required.

What you will learn

  • Explain mazal in a specific context and distinguish astrology from astronomy.
  • Locate the Nisan–Aries–Heh correspondence in the Gra version of Sefer Yetzirah.
  • Compare named Jewish positions and write a reflection grounded in a source.

Before you begin

Start here if you are new to Mazalogy. Have a notebook ready and use a translation you can read comfortably.

Step 01

Give mazal a meaning in context

Read the subject guide and the mazal article. Notice the difference between a congratulatory expression and the question of celestial influence in a rabbinic text. Astronomy measures celestial phenomena; astrology interprets their relation to human affairs.

Next stepFind a month, a sign and a letter

Step 02

Find a month, a sign and a letter

Open chapter 5 of Sefer Yetzirah in the named Gra version. Find the passage connecting Nisan, Aries, Heh and speech. Follow its pattern across month, zodiac and letter before reading a modern interpretation.

Step 03

Hear the argument about influence and choice

Read Rabbi Hanina and Rabbi Yohanan in Shabbat 156a:12, then Maimonides’ rejection of astrological timing in Foreign Worship 11:8–9 and 16. They offer distinct positions and literary settings. Preserve the speaker or author beside every claim.

Next stepMake a source note you can use

Step 04

Make a source note you can use

Choose the Nisan correspondence or another one you have verified in the chapter. Separate what the text connects from the meaning you propose. A reflection activity can focus your attention without assigning a fixed character or future to anyone.

Check your understanding

1. Which note makes the zodiac exercise reproducible?
See the answer and explanation

Sefer Yetzirah, Gra version, chapter 5: Nisan — Aries — ה — speech.

The named text and version let another reader find and examine the relationship. The passage supplies a correspondence; it does not by itself establish a personality claim about people born in that month.

2. How should a summary of Shabbat 156a:12 present Hanina and Yohanan?
See the answer and explanation

As two named positions in a disagreement about mazal.

Hanina affirms celestial influence, while Yohanan denies that Israel is subject to mazal. Preserve the attribution and read the surrounding argument before comparing either voice with Maimonides or a later interpreter.
