Eikev – Mandate and Magnificence

Carl Sagan once observed that “If you wish to make apple pie from scratch, you must first invent the universe.”

There was a long period of history when the idea that the universe had a beginning was shunned by philosophers and scientists, when apple pie didn’t require any universe-inventing.

The upshot of (and perhaps impetus for) believing in such a “steady state” universe was that, without a creation, there was no need for a Creator.

Current scientific belief, based on observational evidence from the 1960s, is that there was indeed a beginning, confirming the truth of the Torah’s very first sentence.

Those bent on keeping a Creator out of the picture resort to fantastical ideas like an “expansion-contraction” model or a “multiple universe” one. They “fear Hashem” – the idea of Hashem.

But objective human beings naturally understand that Hashem exists. Just looking around us, at the miracle called nature, is sufficient proof.

The mitzvah of loving Hashem is repeated in our parshah (Devarim 10:12). And the Rambam (Hilchos Yesodei HaTorah 2:2) explains that it is fulfilled when one meditates on what Hashem has created, on our surroundings and their wonders.

But in Sefer HaMitzvos (Asei 3), he describes love of Hashem as resulting from meditating on His mitzvos. So, is “the way toward love of Hashem” to contemplate His universe, or His commandments?

Rav Mordechai Gifter, zt”l, explained that one statement might be describing the lens; the other, the view. As Rav Mordechai Pogramansky, zt”l, put it in a parable: A visitor to a museum is shown beautiful works of art but is entirely unimpressed. Until someone wipes the thick dust off the fellow’s eyeglasses. Then he’s in awe of the art.

Before one can perceive Hakadosh Baruch Hu’s grandeur in the astounding magnificence of His creation, one must first approach Creation as something other than an accident, as something containing meaning. And the way to attain that foundational, vital recognition is to understand the concept of… mitzvos. That is the lens.

Once we recognize that we have a mandate, it is obvious that there must be a Mandator.

And then, peering through that clear lens at our Mandator-created world, we can perceive its astounding wonders. And thereby come to love the One who created it.

Devarim – Starry, Starry Night

It’s rare for city dwellers to truly see the night sky. Only once, many years ago, driving on a moonless night in West Virginia, did I fully perceive the vast number of stars – nearby planets and distant suns – that were a regular part of people’s lives before the advent of electrical lights.

Although I also (to my shock and delight) saw the Milky Way, the galaxy of which our solar system is part, the billions of individual stars within it cannot be differentiated by the naked eye.

How many stars can be seen with the unaided eye? Hundreds, for certain, maybe even thousands. 

Which leads me to a puzzle. Why are the “stars of the heavens” used by the Torah to mean truly huge numbers? Like in Beraishis 22:17 and Devarim 28:62 and in our parshah (1:10)?

Rashi makes the puzzle even more puzzling: “But were they [the Jewish people] on that day as [many as] the stars of the heavens? Were they not only six hundred thousand?”

In fact, including women and children, they were at least two million. Certainly many more than the stars that our eyes can make out on the starriest of nights.

There are midrashim and commentaries that see the Torah’s star/Jewish People comparisons as indicating something qualitative, not quantitative, like the midrash cited by Rashi on the pasuk in our parshah, which sees the reference indicating Klal Yisrael’s eternal nature. Or Rav Avraham Yitzchak Kook’s suggestion that, just as stars are used for navigation, so are the Jews to live lives to guide other nations, to be a “light unto” them. Perhaps he saw the word larov, “in abundance,” as implying larav, “as a teacher.”  But the word’s simple sense cannot be ignored.

I don’t have an answer to the puzzle, only an observation. Namely, that today we know the Milky Way isn’t a “heavenly river,” as might be the meaning of Nehar Dinur (the “river of light” referenced in Chagigah 14a), some undifferentiated band of light, but rather a collection of billions of stars. And that science, most recently the Webb space telescope, has already revealed unimaginable numbers of stars in untold numbers of galaxies far, far beyond our own.

“Is Anybody There?”

“Is anyone there? Can you hear me?” You shout at the rubble of a collapsed building. No reply, but then… was that tapping?

You have an idea. “If you can understand me,” you yell, “tap once.” A single tap. “If you’re injured,” you then say, “tap twice.” Two taps. There’s someone there.

An apt metaphor for something very important. To read what, please click here.

Parshas V’zos Habracha – Spacewarps

A Roman emperor, according to a Midrashic account (Sifri, Devarim 357), sent two army units to find Moshe Rabbeinu’s burial site. When they stood above it on a hill, they saw it below. When they descended the hill, they saw it above them.

“So, they split up, half above and half below; those above saw it when they looked down, and those below saw it when they looked up.” But neither group could reach the grave.

Which reflects the Torah’s text “No one knows his burial place to this day” (Devarim 34:6).

The space warping recalls that of the aron in which Moshe’s luchos lay.

Rabi Levi (Yoma 21a) notes a mesorah that “the place of the aron is not included in the measurement” – that the kodesh hakadashim measured twenty amos by twenty amos, yet a beraisa states that there were ten amos of space on either side of the aron.

It was there, to be sure, but took up no space.

And Moshe’s grave exists but flips in and out of space.

The idea that space is a given, and cannot be interrupted or bent in any way, was the dominant scientific assumption… until Einstein. Today we know that space, like time, is not a simple unchangeable grid. It can be warped, even torn. And the fact that the assigned place of the Law and the final resting place of the G-d-sent human Lawgiver don’t “fit” space as we know it may mean to telegraph the truth that the Torah, while it was given us in our cozy, seemingly three- (or four, counting time) dimensional universe, encompasses it but exists outside it.

It’s a fitting thought as we transition to the beginning of the Torah, where the first pasuk states that “heaven and earth” were brought into being. Or, as a modern astrophysicist might put it, that space and time themselves came to be, expanding from an unknowable singularity into what we call our universe.

Parshas Vayikra – A Most Meaningful Mineral

The word “sacrifices” used for korbanos, the mainstay topic of parshas Vayikra, is a misnomer. Korban doesn’t carry the meaning of “giving up something.” Its most accurate, if awkward, translation would be “bringer of closeness.”

How closeness is effected by korbanos may have to do, at least in a simple sense, with the hierarchy of creation noted in many Jewish sources, domeim, tzomei’ach, chai, medaber: “still” (mineral), “growing” (vegetation), “living” (animal) and “speaking” (human). 

By establishing the korban-bringer as subjugating and employing the lower realms (which are all represented in korbanos), he is placing himself closer to Hashem, in Whose image he was created.

Interestingly, the “still,” or mineral component of korbanos, is a necessary component of all korbanos, both animal and vegetable (i.e. menachos, or flour offerings): salt.   “On your every offering shall you offer salt” — Vayikra 2:13).

Rishonim like Ramban and Rabbeinu Bachya, who assert that salt is a combination of water and fire may have based that description on the simple observation of the fact that salt can be obtained through saltwater and that salt can “burn” vegetation and skin. Or maybe the description is meant as symbolic and is part of a mystical mesorah.

But whatever the source of their assertion, they see salt as representing a combination of opposites, of antagonists, which informs the use in parshas Vayikra of the word bris, or “covenant,” in the pasuk quoted above, to refer to the mineral.

The Kli Yakar explains that the “covenant [of opposites]” that salt represents conveys the idea that Dualist philosophies like Manichaeism are false. Hashem is King over all; what may seem like irreconcilable opposites are all ultimately under His control. 

I find it intriguing that, in the paradigm of contemporary physics, salt is indeed a compound of two disparate (if not “opposite,” whatever that might mean in the periodic table) elements: sodium and chlorine.  Both are highly reactive. (Countless chemistry teachers got the attention of their students by dropping a piece of sodium into a container of water.) 

And each is invariably fatal if ingested. Both, in other words, are poisons.

And yet, the ionic compound that results from the two elements’ “covenant” is a mineral that is necessary for life, that flavors our food, that preserves perishables… and that must be part of every korban

Plumbing the Meaning of the Torah’s First Word

The Torah’s first verse is purposely unclear.  As the Ramban, Nachmanides, points out, the deepest truths of how the universe was created are unfathomable and inscrutable, hidden, ultimately, in the realm of mysticism, not physical science.

It is intriguing, though, that the Torah’s first word, “Bereishis,” implies, as the Seforno explicitly states, that time itself is a creation – a notion that comports with traditional cosmological physics (if not with scientists who, terrified at the notion of a “beginning,” postulate a “multiverse” of universes, conveniently beyond observation).

Likewise intriguing is that, according to the Talmud, the Torah’s first word can be split into two words, “bara” and “shis.”  While the Gemara sees in “shis” a hint to an Aramaic word meaning “conduit,” hinting to an underground channel into which liquid poured on the mizbe’ach would descend (a channel created at the beginning of time – Sukkah, 49a), the word can also, most simply, mean “six.”

As in the six types of quarks, currently believed to be the fundamental particles of which all matter is, ultimately, comprised.

“He created six”?
