# Fractal Patterns in the Torah

In the Torah portion *Emor *(Leviticus 21:1–24:23), we are instructed to abstain from work every seventh day on Shabbat. Next week’s Torah portion, *Behar*, continues this theme and instructs us to abstain from agricultural work every seventh Sabbatical year, *Shmita*. And the Torah doesn’t stop there. It instructs us to count seven *Shmitas* and then observe a Jubilee, *Yovel*.

Do you notice a pattern? Every seven days, every seven years, every seven *Shmitas*… Furthermore, the Midrash states the world will exist for seven thousand years with the seventh millennium being a thousand years of the kingdom of *Mashiach* (Messiah)—*yom shekuloy Shabbat—*one long *Shabbat*. A second-century sage, Rabbi Huniah ben HaKanah, interprets this *Midrash* to mean that the world will last seven Cosmic *Shmitas*, i.e., 49 thousand years (which, according to a prominent 13th–14th c. kabbalist Rb. Isaac of Acre, speaks not of terrestrial years but of celestial years that are equivalent to approximately 15 billion years—not far from the current estimate of the cosmological age of the universe of 13.8 billion years, but this is another topic.)

What is common here is self-similarity on different scales—number seven plays a role of a period in a multidimensional spiral with multiple periods: seven days, seven years, seven *shimitas* (strictly speaking, seven *shmitas* plus one, as Jubilee is every 50th year), seven millennia, seven Cosmic *Shmitas*… In mathematics, such patterns are called fractals. A fractal, by definition, is a pattern that repeats itself on every scale. This property is called self-similarity.

Fractal geometry is a fascinating and relatively new area of mathematics. Some of the simplest examples of fractal sets are:

**Cantor set**. To construct a Cantor set, we first draw a line. We divide this line into three segments and remove the middle segment. We continue this procedure *ad infinitum*. Here is a Cantor set for seven iterations:

**Koch Snowflake**. The Koch snowflake can be constructed by starting with an equilateral triangle, then recursively changing each line segment as follows:

- We divide the line segment into three segments of equal length.
- Then we draw an equilateral triangle that has the middle segment from step 1 as its base and points outward.
- Finally, we remove the line segment that is the base of the triangle from step 2.

We repeat this process *ad infinitum*. You can’t help but notice that the second iteration of the algorithm produces the Star of David, *Magen David*. An amazing property of the Koch snowflake is that it has a finite area bounded by an infinitely long line.

**Sierpinski Triangle**. This fractal is an equilateral triangle, subdivided recursively into smaller equilateral triangles.

It is constructed by removal of triangular subsets:

- We start with an equilateral triangle.
- We subdivide it into four smaller equilateral triangles and remove the central one.
- Then we repeat step 2 with each of the remaining smaller triangles, and so on.

**Sierpinski Carpet:**

Sierpinski Carpet is very similar to the Sierpinski Triangle where instead of triangles, we use squares:

**Fractal Canopy**. A fractal canopy has the following three properties:

- The angle between any two neighboring line segments is the same throughout the fractal.
- The ratio of lengths of any two consecutive line segments is constant.
- Points all the way at the end of the smallest line segments are interconnected.

The common thread of all these images is self-similarity on every scale. Some fractals are hypnotically beautiful. Take a look, for example at this Julia Set fractal:

Fractal shapes exist not only in mathematics, but they are also all around us. Jewish mathematician Benoit Mandelbrot noticed that much of nature has fractal shape—be that a maple leaf, cauliflower, mountains, coastline, lungs, or blood vessels—they all share one property, self-similarity on various scales. (A few years ago, I hypothesized that our spacetime, while smooth on a large scale, must be fractal on micro-scale. If true, this fractal “roughness” on a small scale may be able to bridge the gap between general relativity and quantum field theory.) Fractals are ubiquitous in nature. Why is that?

It seems to me that the reason for that lies in the structure of *sefirot *in the world of *Tikun* (Rectification). *Sefirot—*divine emanations that are the “building blocks” of creation—are the underlying conceptual framework of the entire creation. While in the world of *Tohu* (Chaos) *sefirot* are disjointed, which led to *shevirat hakelim* (breaking of the vessels), in the world of *Tikun* they are inter-included, i.e., each *sefirah* includes all ten *sefirot*. Thus, *Chochmah* includes all ten *sefirot*: *Chokhmah* of *Chokhmah*, *Binah* of *Chokhmah*, *Daat* of *Chokhmah*, *Chesed* of *Chokhmah*, *Gevurah* of *Chokhmah*, *Tiferet* of *Chokhmah*, *Netzach* of* Chokhmah*, *Hod* of *Chokhmah*, *Yisod* of *Chokhmah* and *Malchut* of *Chokhmah*. Ten *sefirot* branch out into 100 combinations. We are now in the days of counting of the Omer, when each day we repair a particular combination of seven *midot* (seven lower *sefirot*) counting *Chesed* of *Chesed*, *Gevurah* of *Chesed*, etc.—49 permutations in total. Each of the 100 combinations, in turn, further includes each of the ten *seferiot* resulting in further branching of the *sefirotic* tree, *ad infinitum*. This is a perfect fractal structure. No wonder that the physical world, reflecting its spiritual origin, exhibits similar fractal patterns. Whereas nature furnishes plentiful examples of fractal patterns in space, the Torah shows us a unique fractal pattern in time and in the spiritual domain.

Another fractal pattern unique to Torah is found in one of the tools of biblical hermeneutics—*gematriah*. In Hebrew, the numbers are written using the letters of the *Alef Bet*: 1 is *Alef*, 2 is *Bet*, etc. Thus, every Hebrew letter has a numerical value, *gematriah*. To simplest way to calculate the *gematriah* of a Hebrew word, one adds the numerical values of all letters spelling out that word. For example, the word *achad* (one) is spelled *Alef-Chet-Dalet*. The numerical values of these letters are: *Alef*=1, *Chet*=8 and *Dalet*=4. Thus, the gematriah of *ahad* is 1+8+4=13. However, each letter has its name and, therefore, its own *gematriah*: *Alef* is spelled *Alef-Lamed-Peh*, so it’s *gematriah* is 1+30+80=111. *Chet* is spelled *Chet-Yud-Tav*, so its *gematriah* is 8+10+400=418. *Dalet* is spelled *Dalet-Lamed-Tav*, so its *gematriah* is 4+30+400=434. Expanding each letter of the word *achad* with the spelling of each letter gives *Alef-Lamed-Peh-Chet-Yud-Tav-Dalet-Lamed-Tav*, so the expanded *gematriah *of *achad* is 111+418+434=963. Such *gematriah* is called *milui* (filled). Each letter in the expanded, *milui, *spelling can, in turn, be spelled out again, *ad infinitum*. Once again, we have a fractal pattern.

The entire Torah hermeneutics is fractal in nature. There are five levels of Torah interpretation called by their acronym, Pardess (garden):

*Pshat*(literal meaning)*Remez*(hint)*Drash*(homiletics)*Sod*(“secret” – Kabbalah)*Sod sheb’Sod*(“Secret of Secrets”—Chasidut)

In turn, each of these levels also has five levels, so that we have *Pshat *of* Pshat, Remez *of* Pshat*. etc.—a fractal structure.

On a broader scale, God created a man and woman in His image. He further commanded them to procreate. This has set off the ever-growing, ever-branching tree of humanity. As Benoit Mandelbrot explained, a fractal is a “shape having the property that each small portion can be viewed as a reduced scale replica of the whole.” When looking at a person, no matter how small, we should never forget that this is a miniature replica of God. Let’s show some respect!
