Yehi Ohr and Unfolding the Name of 42

“In the beginning, God created the heavens and the earth. Now the earth was unformed and void, and darkness was upon the face of the deep,
and the spirit of God was hovering over the face of the waters…” Genesis 1:1-2.

Then G-d said, Yehi Ohr (“Let there be light”) Not the gentle glow of dawn nor the shimmer of stars, but something more primal, more violent, more absolute—the very first unshackling of energy from form, the first cry of existence from the womb of silence. This light is not mere light. It is not a metaphor. It is not just poetry. It is something that both science and mysticism affirm as real: that the First Light still echoes through the vastness of the cosmos.

Physicists might see evidence of it in the cosmic microwave background — CMB for short. It is not light as we see it now, but a violent torrent of radiation, stretched by time and space into a near-invisible murmur, permeating everything. It is the afterglow of what modern science terms the Big Bang—the remnant radiation from the moment the universe first became transparent to light, some 380,000 years after its initial burst into being.

Before this, light could not move freely. The universe was dense, hot, a seething plasma of particles and photons locked in constant collision. But then, it cooled just enough for atoms to form. Electrons embraced protons, and suddenly the cosmos opened its eyes.

That moment is called recombination in cosmology, but in the language of mysticism, it might better be called revelation. For the first time, the universe could be seen from within and without. The Light was loosed. The veils parted. Creation stepped across a threshold into visibility.

And yet, this view of beginnings—singular, absolute, unprecedented — is not the teaching of our sages.

In the Book of Genesis, there is a mysterious and lengthy passage:

“וְאֵלֶּה הַמְּלָכִים אֲשֶׁר מָלְכוּ בְאֶרֶץ אֱדוֹם לִפְנֵי מְלֹךְ מֶלֶךְ לִבְנֵי יִשְׂרָאֵל… וַיָּמָת”

“And these are the kings who reigned in the land of Edom before there reigned any king over the children of Israel… and he died.” (Bereishit 36:31–39)

There were eight kings in total, seven of whom “reigned and died”– the eighth king, Hadar, represents our current universe:

1. Bela ben Be’or — “And Bela the son of Beor reigned in Edom… And Bela died.”

2. Yovav ben Zerach — “And Yovav the son of Zerach of Batzrah reigned in his stead… And Yovav died.”

3. Chusham of the land of the Temani — “And Chusham reigned in his stead… And Chusham died.”

4. Hadad ben Bedad — “And Hadad the son of Bedad reigned in his stead… And Hadad died.”

5. Samla of Masrekah — “And Samla reigned in his stead… And Samla died.”

6. Shaul of Rechovot HaNahar — “And Shaul reigned in his stead… And Shaul died.”

7. Baal Chanan ben Achbor — “And Baal-Chanan the son of Achbor reigned in his stead… And Baal-Chanan died.”

8. Hadar — “And Hadar reigned in his stead, and the name of his city was Pau…”

The Zohar and the teachings of the Ari explain this list as a cosmic allegory: these kings who reigned and died represent prior worlds, prior universes, created and destroyed before our own. Seven kings, seven deaths — seven worlds that shattered. These are not mythic fables. They are profound ontological truths encoded in Torah’s language.

Creation, according to Kabbalah, is not a one-time event. It is cyclical. Rhythmic. Worlds are born, they expand, they shatter, they fall—and from their fragments, new worlds arise. The concept of שבירת הכלים—the shattering of the vessels—is central to Lurianic cosmology. The light that was too vast for its first containers tore them apart, and their broken shards fell into the lower worlds. Ours is one such world: built from the fragments of those earlier attempts, bearing within it both the trauma of collapse and the potential for restoration.

In this respect, Kabbalah does not affirm the Big Bang as the singular beginning of all. It sees this phase — what science recognizes as the expansion and cooling of the current universe—as the latest unfolding in a longer, deeper, more mysterious cycle. The CMB is not the echo of the first creation, but perhaps the most recent one—the last great letting of light into a cosmos reborn from wreckage.

This is the same primordial light of which it is said in Genesis: יְהִי אוֹר—“Let there be light.” And there was light—וַיְהִי אוֹר. But this was not the light of sun or moon, which were not created until the fourth day. This was an earlier light, the Or HaGanuz, the hidden light, stored away for the righteous in the world to come. It was too pure, too infinite, too whole to remain exposed in a fractured world.

The Zohar says that this light “shone from one end of the universe to the other.” It was a light that “revealed all,” a radiance that flooded being before separation had set in. In the cosmology of the Ari, this light emerges only after the Tzimtzum—the great contraction of Infinite Being to make space for finitude. Into that womb of darkness came the light, channeled through vessels that could not bear it.

And when they shattered, the light spilled into realms not yet ready to receive it. This is the root of brokenness, but also the beginning of repair.

Modern science calls this aftermath the early universe. And what it sees, with radio telescopes and deep-sky detectors, is astonishingly consistent with the mystical vision. The CMB is not random. It bears the imprint of structure, the faint fingerprints of galaxies not yet born. It is a map of potential, a memory of intention. The anisotropies — the tiny variations in temperature — are the seeds of stars, of planets, of consciousness. They are the echo of order forming from chaos.

And they are still with us. The CMB is everywhere. It fills every inch of space, every corner of night. When your radio hisses between stations, a fraction of that static is the voice of the beginning. It is older than stars, older than atoms. It is the breath of creation still reverberating through the lungs of the cosmos.

In Greek philosophy, light was seen as the primal element—the bridge between the ideal and the visible. Plato spoke of the Good as that which enables both knowledge and existence, much as light enables sight and being. In Indian metaphysics, jyoti—divine light—is the first manifestation of the Absolute. And in Islamic mysticism, the Light Verseof the Qur’an speaks of the divine as “the Light of the heavens and the earth.” Across cultures and centuries, this intuition has endured: that light is not merely a physical phenomenon, but a spiritual archetype.

But now, with instruments forged of silicon and cooled with liquid helium, we glimpse this light anew. We no longer need to guess what the First Light looked like. We have seen its traces. The satellite COBE first sketched its form; WMAP refined it; Planck revealed it in exquisite detail. And what we see is harmony. Not perfection, but intent—the possibility of form arising from formlessness, of symmetry breaking just enough to let beauty arise.

This is the face of Bereshit. This is the canvas upon which all future color is painted.

And yet, that light is cold now. Just 2.7 degrees above absolute zero. It is not the blazing fire of genesis but its whispering ghost. It tells us that the beginning is not gone, only hidden—like the Or HaGanuz, the concealed light of the mystics.

We live in the world of concealment, of garments upon garments, yet the echo of that first brilliance still lingers. Every photon of the CMB has traveled billions of years to reach us. It has never been absorbed, never collided, never forgotten where it came from. It is testimony. It is memory. It is the universe, remembering its first breath.

And so we look up, and we listen. With instruments of science and hearts of longing. And when we feel lost in the vastness, when exile feels permanent and darkness thick, we can remember: The light is still here. It is cold, yes, and distant. But it is here. Wrapped around us like a second skin, a veil of first memory.

And perhaps, just perhaps, one day we will learn again how to see it.
