Sefer Yetzirah

Sefer Yetzirah(Hebrew:סֵפֶר יְצִירָה‎Sēp̄er Yəṣīrā,Book of Formation,orBook of Creation) is the title of a book onJewish mysticism.Early commentaries, such as theKuzari,treated it as a treatise on mathematical and linguistic theory as opposed toKabbalah.The wordYetzirahis more literally translated as "Formation"; the wordBriahis used for "Creation".The book is traditionally ascribed to the patriarchAbraham,although others attribute its writing toRabbi Akiva.Modern scholars have not reached consensus on the question of its origins. According to RabbiSaadia Gaon,the objective of the book's author was to convey in writing how the things of our universe came into existence.Conversely,Judah Haleviasserts that the main objective of the book, with its various examples, is to give to man the means by which he is able to understand the unity and omnipotence of God, which appear multiform on one side and, yet, are uniform.

The famous opening words of the book are as follows:

By thirty-two mysterious paths of wisdom Yah has engraved [all things], [who is] the Lord of hosts, the God of Israel, the living God, the Almighty God, He that is uplifted and exalted, He that Dwells forever, and whose Name is holy; having created His world by three [derivatives] of [the Hebrew root-word]s^ef^ar:namely,sefer(a book),sefor(a count) andsippur(a story), along with ten calibrations of empty space, twenty-two letters [of the Hebrew Alpha bet], [of which] three are principal [letters] (i.e.א מ ש‎), seven are double-sounding [consonants] (i.e.בג "ד כפר" ת‎) and twelve are ordinary [letters] (i.e.ה ו ז ח ט י ל נ ס ע צ ק‎).

Origin

A cryptic story in theBabylonian Talmudstates,

On the eve of everyShabbat,Rav HaninaandRav Hoshaiahwould sit and engage in study ofSefer Yetzirah,and create a deliciouscalfand eat it.

Mystics assert that the biblical patriarch Abraham used the same method to create the calf prepared for the three angels who foretoldSarah's pregnancy in the biblical account at Genesis 18:7.All the miraculous creations attributed to otherrabbisof the Talmudic era are ascribed by rabbinic commentators to the use of the same book.

Sefer Yetzirah's appendix (6:15) declares that Abraham was the recipient of the divine revelation of mystic lore; so that the rabbis of the classical rabbinic eraand philosophers such asShabbethai DonnoloandJudah HaLevinever doubted that Abraham was the author of the book.

InPardes Rimonim,Moses ben Jacob Cordovero(Ramak) mentions a minority opinion thatRabbi Akivaauthored it, and takes it to mean Abraham wrote it and Akiva redacted it to its current form.Jewish Lore attributes it toAdam,and that "[f]rom Adam it passed over toNoah,and then to Abraham, the friend of God. "

In a manuscript in theBritish Museum,theSefer Yetzirahis called theHilkot Yetzirahand declared to be esoteric lore not accessible to anyone but the really pious.

Academic dating

According to modern historians, the origin of the text is unknown, and hotly debated. Some scholars believe it might have an early medieval origin,while others emphasize earlier traditions appearing in the book.Most contemporary scholars date the text's authorship to theTalmudicperiod.

According to the Jewish Encyclopedia, the essential elements of the book are characteristic of the 3rd or 4th century; for a work of this nature, composed in theGeonicperiod, could have been cast only in the form of Jewish gnosis, which remained stationary after the 4th century, if indeed it had not already become extinct.The historical origin of theSefer Yetzirahwas placed byRichard August Reitzensteinin the 2nd century BCE.According to Christopher P. Benton, the Hebrew grammatical form places its origin closer to the period of theMishnah,around the 2nd century CE.

The division of the letters into the three classes of vowels, mutes, and sonants also appears inHellenictexts.

The date and origin of the book can not be definitely determined so long as there is no critical text of it. Theeditio princeps(Mantua,1562) contains two recensions, which were used in the main by the commentators of the book as early as the middle of the 10th century. The shorter version (Mantua I.) was annotated byDunash ibn Tamimor byJacob ben Nissim,while Saadia Gaon and Shabbethai Donnolo wrote commentaries on the longer recension (Mantua II.). The shorter version was also used by most of the later commentators, such asJudah ben BarzillaiandNachmanides,and it was, therefore, published in the ordinary editions. The longer recension, on the other hand, was little known, the form given in theeditio princepsof theSefer Yetzirahbeing probably a copy of the text found in Donnolo's commentary. In addition to these two principal recensions of the text, both versions contain a number of variant readings that have not yet been examined critically.

As regards the relation of the two recensions, it may be said that the longer form contains entire paragraphs which are not found in the shorter, while the divergent arrangement of the material often modifies the meaning essentially. Although the longer recension doubtless contains additions and interpolations which did not form part of the original text, it has many valuable readings which seem older and better than the corresponding passages in the shorter version, so that a critical edition of the text must consider both recensions.

Manuscripts

Title Page of Sefer Yetzirah, Mantua, Italy, 1562

TheSefer Yetzirahexists in many manuscripts, generally falling in categories known as:

1. The Short Version,
2. The Long Version,
3. The Saadia Version, and
4. The Gra Version

The long version contains entire paragraphs which are not found in the short version, while the divergent arrangement of the material often modifies the meaning essentially.The short version comprises about 1300 words and was annotated byDunash ibn Tamim,and it formed the basis of the first printed Hebrew edition, published in Mantua in the year 1562, and most main versions printed thereafter. The long version is 2500 words and is present with a commentary byShabbethai Donnolo.It is frequently printed with this commentary as an appendix to editions of the short Version. In the 13th century,Abraham Abulafianoted the existence of both of these versions.

The Mantua 1562 edition was printed with the short version surrounded by commentaries attributed toAbraham ben David(outside of the page),Nachmanides(bottom of the page) andMoses Botarel(inside of the page; the printer notes that Botarel followed the first two rabbis and also collected all other commentaries that preceded him). An appendix following this contains a pair of commentaries printed side by side, one attributed toEleazar of Worms) on the outside of the pages and the other toSaadia Gaonon the inside of the pages. At the end of the volume is found the long version.

In the middle of the 16th century, the leader of the school of Safed kabbalists,Moses Cordovero,established a working text based on ten separate manuscripts. His student and successorIsaac Luriafurther redacted this to harmonize it with theZohar,and then in the 18th century, theVilna Gaon,known as "the Gra", further redacted it. This text is called the Gra or ARI-Gra version.

In the 10th century, Saadia Gaon wrote his commentary based on a manuscript which was a reorganized copy of the Longer Version, now called the "Saadia Version". This was translated into French by Lambert and thence into English by Scott Thompson. This version and commentary was more philosophical in nature rather than mystical and had virtually no impact on subsequent kabbalists.

Influence

TheSefer Yetzirahis devoted to speculations concerning God's creation of the world. The ascription of its authorship to the biblical patriarchAbrahamshows the high esteem which it enjoyed for centuries. It may even be said that this work had a greater influence on the development of the Jewish mind than almost any other book after the completion of theTalmud.

TheSefer Yetzirahis exceedingly difficult to understand on account of its obscure style. The difficulty is rendered still greater by the lack of a critical edition, the present text being much interpolated and altered.Hence there is a wide divergence of opinion regarding the age, origin, contents, and value of the book.

Jewish study

The history of the study of theSefer Yetzirahis one of the most interesting in the records of Jewish literature. With the exception of the Bible, scarcely any other book has been the subject of so much annotation.

An intimate relation exists between theSefer Yetzirahand the later mystics; and although there is a marked difference between the later Kabbalah and theSefer Yetzirah(for instance, thesefirotof the Kabbalists do not correspond to those of theSefer Yetzirah), the system laid down in the latter is the first visible link in the development of Kabbalistic ideas. Instead of the immediate creationex nihilo,both works postulate a series of emanations of mediums between God and the universe; and both consider God as the first cause only, and not as the immediate efficient cause of the world.

A book of the same name was circulated among theAshkenazi Hasidimbetween the 11th and 13th centuries, for whom it became a source ofPractical Kabbalah.This book seems to be a mystic work on the six days of creation, and corresponded in part to the smallmidrash,Seder Rabbah deBereshit.

In Thelema

Teachings

Structure

Sefer Yetzirahdescribes how the universe was created by the "God of Israel" (a list of all ofGod's Hebrew namesappears in the first sentence of the book) through "32 wondrous ways of wisdom":

• Ten Numbers(Sefirot,the origin for theSefirotof later Kabbalah)
• TheTwenty-Two Lettersof the Hebrew Alpha bet—
  • Three"Mother" Letters(Aleph,Mem,Shin)
  • Seven"Doubles"(Bet,Gimel,Dalet,Kaph,Pe,Resh,Taw)
  • Twelve"Simples"or"Elementals"(He,Waw,Zayin,Heth,Teth,Yodh,Lamedh,Nun,Samekh,Ayin,Tsade,Qoph)

These 32 divisions correspond to: the 22Hebrew Letters,the 10numbers,the 10Divine Namesof God, theTetragrammaton,theHebrew Calendar(7 days & 12 months), theSolar System(7 visibleplanets& 12 constellations of thezodiac), the12 Tribes of Israel,12 Boundaries(EastUp/ENorth/ELow),Space(Above/Below, Up/Down, East/West, North/South, Left/Right),Time(Day-Night, Hours, & Past/Present/Future), the 4 Classical GreekElements(Air, Earth, Fire, Water), theHuman Body(Head/Arms/Legs/etc.), the variousHuman Body Functions,theMentalFoundations(Speech/Thought/Motion/etc), theMystical Experience(negation of self outside of Time) riding theTeli/Dragonon theMerkava(Chariot), and the functionFactorial(eg. 6! =1x2x3x4x5x6=720).

The book describes the method to use the 10 Sefirot and the 22 Hebrew Letters to gain a Divine Insight/Secret using Abraham's tongue. God's covenant with Abraham is described as being two-fold:

1. The "covenant of the circumcision"(in Hebrew:mila<מִילָה‎> means "word") is between the 10 toes of the feet.
2. The "covenant of the tongue"(in Hebrew: lashon<לָשׁוֹן>means "language") is between the 10 fingers of the hand.

The book's ending connects theTorah's Divine Hebrew Letters and the tongue of Abraham revealing its Secret to Abraham.

The phonetic system

Thephilologicalis discussed first, since it is necessary for an elucidation of the philosophical speculations of the work. The twenty-two letters of theHebrew Alpha betare classified both with reference to the position of the vocal organs in producing the sounds, and with regard to sonant intensity. In contrast to the Jewish grammarians, who assumed a special mode of articulation for each of the five groups of sounds, theSefer Yetzirahsays that no sound can be produced without the tongue, to which the other organs of speech merely lend assistance. Hence the formation of the letters is described as follows:

• With the tip of the tongue and the throat
• Between the lips and the tip of the tongue
• In the middle of the tongue
• By the tip of the tongue
• By the tongue, which lies flat and stretched, and by the teeth (ii. 3)

The letters are distinguished, moreover, by the intensity of the sound necessary to produce them, and are accordingly divided into:

• Mutes,which are unaccompanied by sound, such as Mem
• Sibilants,such as Shin, which is therefore called the "hissing shin"
• Aspirates,such as Aleph, which holds a position between the mutes and sibilants, and is designated as the "airy Aleph, which holds the balance in the middle" (iv. 1; in some eds. ii. 1)

Besides these three letters, which are called "mothers," a distinction is also drawn between the seven "double" letters, which have two different sounds according to inflection, and the twelve "simple" letters, the remaining characters of the Alpha bet which represent only one sound each.

Themes

Both the macrocosm (theuniverse) and the microcosm (human) are viewed in this system as products of the combination and permutation of these mystic characters,and such a use of the letters by the Jews for the formation of theHoly Nameforthaumaturgicalpurposes is attested by magic papyri that quote an "Angelic Book of Moses", which was full of allusions tobiblicalnames.

The linguistic theories of the author of theSefer Yetzirahare an integral component of its philosophy, its other parts being astrological andGnosticcosmogony.The three letters Aleph, Mem, Shin, are not only the three "mothers" from which the other letters of the Alpha bet are formed, but they are also symbolic figures for the three primordial elements, the substances which underlie all existence.

According to theSefer Yetzirah,the first emanation from the spirit of God was theruach(רוּחַ‎rúaħ"spirit", "air" ) that produced water, which, in its turn, formed the genesis of fire. In the beginning, however, these three substances had only a potential existence, and came into actual being only by means of the three letters Aleph, Mem, Shin; and as these are the principal parts of speech, so those three substances are the elements from which the cosmos has been formed.

The cosmos consists of three parts, the world, the year (or time), and man, which are combined in such a way that the three primordial elements are contained in each of the three categories. The water formed the earth; heaven was produced from the fire; and theruachproduced the air between heaven and earth. The three seasons of the year--winter, summer, and the rainy season--correspond to water, fire, andruachin the same way as man consists of a head (corresponding to fire), torso (represented byruach), and the other parts of the body (equivalent to water).

The seven double letters produced the seven planets, the "seven days," and the seven apertures in man (two eyes, two ears, two nostrils, and one mouth.) Again, as the seven double letters vary, being pronounced either hard or soft, so the seven visible planets are in continuous movement, approaching or receding from the earth. The "seven days," in like manner, were created by the seven double letters because they change in time according to their relation to the planets. The seven apertures in man connect him with the outer world as the seven visible planets join heaven and earth. Hence these organs are subject to the influence of the planets, the right eye being under Saturn, the left eye under Jupiter, and the like.

The twelve "simple" letters were used to create the twelve signs of the zodiac, whose relation to the earth is always simple or stable; and to them belong the twelve months in time, and the twelve "leaders" in man. The latter are those organs which perform functions in the body independent of the outside world, being the hands, feet, kidneys, gall, intestines, stomach, liver, pancreas, and spleen; and they are, accordingly, subject to the twelve signs of the Zodiac.

In its relation to the construction of the cosmos, matter consists of the three primordial elements; they are not chemically connected with one another, but modify one another only physically. Power (δύναμις) emanates from the seven and the twelve heavenly bodies, or, in other words, from the planets and the signs of the zodiac. The "dragon" rules over the world (matter and the heavenly bodies); the sphere rules time; and the heart rules over the human body. The author sums up this explanation in a single sentence: "The dragon is like to a king on his throne, the sphere like a king traveling in his country, and the heart like a king at war."

Creation

To harmonize theGenesis creation narrative,which is acreatio ex nihilo,with the doctrine of the primordial elements, theSefer Yetzirahassumes a double creation, one ideal and the other real.

Their name is possibly derived from the fact that as numbers express only the relations of two objects to each other, so the tensefirotare only abstractions and not realities. Again, as the numbers from two to ten are derived from the number one, so the ten Sefirot are derived from one "their end is fixed in their beginning, as the flame is bound to the coal" (i. 7). Hence theSefirotmust not be conceived as emanations in the ordinary sense of the word, but rather as modifications of the will of God, which first changes to air, then becomes water, and finally fire, the last being no further removed from God than the first. The Sefer Yetzirah shows how the sephirot are a creation of God and the will of God in its varied manifestations.

Besides these abstract ten sefirot, which are conceived only ideally, the twenty-two letters of the Alpha bet produced the material world, for they are real, and are the formative powers of all existence and development. By means of these elements the actual creation of the world took place, and the ten sefirot, which before this had only an ideal existence, became realities. This is, then, a modified form of the Talmudic doctrine that God created heaven and earth by means of letters (Berakhot58a). The explanation on this point is obscure since the relation of the twenty-two letters to the ten sefirot is not clearly defined.

The first sentence of the book reads: "Thirty-two paths, marvels of wisdom, hath God engraved...," these paths being then explained as the ten sefirot and the twenty-two letters. While the sefirot are expressly designated as "abstracts", it is said of the letters: "Twenty-two letters: God drew them, hewed them, combined them, weighed them, interchanged them, and through them produced the whole creation and everything that is destined to come into being" (ii. 2).

The letters are neither independent substances nor yet as mere forms. They seem to be the connecting-link between essence and form. They are designated as the instruments by which the real world, which consists of essence and form, was produced from the sefirot, which are merely formless essences.

Theories of contrast in nature

In addition to the doctrine of theSefirotand the letters, the theory of contrasts in nature, or of thesyzygies( "pairs" ), as they are called by the Gnostics, occupies a prominent place in theSefer Yetzirah.This doctrine is based on the assumption that the physical as well as the spiritual world consist of pairs mutually at war, but equalized by the unity, God. Thus in the three prototypes of creation the contrasting elements fire and water are equalized by air; corresponding to this are the three "Rulers" among the letters, the mute Mem contrasting with the hushing Shin, and both being equalized by Aleph.

Seven pairs of contrasts are enumerated in the life of man:

• Life and death
• Peace and war
• Wisdom and folly
• Wealth and poverty
• Beauty and ugliness
• Fertility and sterility
• Lordship and servitude (iv. 3).

From these premises theSefer Yetzirahdraws the important conclusion that subjective "good and evil" have no real existence, for since everything in nature can exist only by means of its contrast, a thing may be called good or evil according to its influence over man by the natural course of the contrast.

The book teaches that man is a free moral agent, and therefore a person is rewarded or punished for his or her actions. While the ideas ofheavenandhellare left unmentioned in the book, it teaches that the virtuous man is rewarded by a favorable attitude of nature, while the wicked man finds it hostile to him.

Gnostic elements

Sefer Yetzirahis similar to various Gnostic systems. As theSefer Yetzirahdivides theHebrew Alpha betinto three groups, so the GnosticMarcusdivided the Greek letters into three classes, regarded by him as the symbolic emanations of the three powers which include the whole number of the upper elements.

Both systems attach great importance to the power of the combinations and permutations of the letters in explaining the genesis and development of multiplicity from unity. TheClementine writingspresent another form of gnosis which agrees in many points with theSefer Yetzirah.As in the latter, God is not only the beginning but also the end of all things, so in the former He is the ἀρχή (= ראשית) and τέλος (= תכלית) of all that exists; and the Clementine writings furthermore teach that the spirit of God is transformed into πνεῦμα (= רוח), and this into water, which becomes fire and rocks, thus agreeing with theSefer Yetzirah,where the spirit of God, רוח (= πνεῦμα), air, water, and fire are the first fourSefirot.

The remaining sixSefirot,or the limitations of space by the three dimensions in a twofold direction, are also found in the Clementina, where God is described as the boundary of the universe and as the source of the six infinite dimensions.

The "dragon"(תליtli,perhaps meaning "curled one" as a coiled serpent) which plays such an important part in theastrologyof the book, is probably an ancient Semitic figure; at all events its name is not Arabic, as scholars have hitherto assumed, but either Aramaic or possibly a Babylonian loan-word.The "dragon" is often understood as the starry constellationDracoand by extension it represents the cosmic axis (equivalent to the north/south pole) because this constellation coils around theNorth Starand thus around the celestial axis, as it intersects the northernmost part of thecelestial sphere.

Factorial

In discussing the number of words that can be formed from theHebrew Alpha bet,Sefer Yetzirah includes one for the earliest known descriptions of the mathematical functionfactorial,enumerating its first seven values and emphasizing its rapid growth.
