A Wheel Within a Wheel

Now as I beheld the Chayot [living creatures], behold one Ophan [wheel] at the bottom hard by the living creatures, at the four faces thereof. The appearance of the Ophanim [wheels] and their work was like unto the colour of a beryl; and they four had one likeness; and their appearance and their work was as it were a wheel within a wheel. . . . As for their rings, they were high and they were dreadful; and they four had their rings full of eyes round about. Ezekiel 1:15–18 One of the most difficult theological questions is how Eternal God relates to the world created by Him, the world that is always in flux. Indeed, the prophet Malachi says in the name of God: For I the Eternal change not.Malachi 3:6 God does [...]

Lag BaOmer Tragedy

A day of joyful festivities turned into a day of tears and mourning. When tragedy strikes, it is not the time for analysis or finger-pointing. Rather, it is the time to bury the dead and to mourn. It is the time to comfort families of the deceased. it is the time to pray that those who survive may fully recover. However, the tragic irony of this disaster is that it happened to the devout who came to the kever (burial place) of Rabbi Shimon bar Yochai, known as the Rashbi, the second-century tana, to pray for miracles. It happened on Lag BaOmer—the day of the Rashbi's passing, a day believed to be an auspicious one to pray for miracles. How does one explain to children that people who came to the tomb of [...]

Sanctuaries in Space and Time

We are quite familiar with space—we move freely in space back and forth; we concur space on land and beyond; we reclaim land from sea; we turn deserts into gardens; we turn desolated space into sprawling cities. We are, on the other hand, helpless in the face of time. We cannot move freely in time. We can’t move back in time. We are swept forward in the inexorable flow of time. We do not understand time; we cannot change it. We are masters of land, but not of time. It is for this reason, when God instructed Moses how to build a sanctuary for Himself, He could not have started with time—we would have not the faintest idea what it meant—a sanctuary of God in time—let alone how to do it. That is why God started with space, instructing Moses how to build the Mishkan—a Sanctuary in space—first. Only then He commanded Moses about Shabbat.

Collapse and Revelation

The collapse of the wave function is the process of revealing hidden possibilities. Reducing uncertainty reveals information. Until the wave function collapse, the system is in an uncertain state—the state of superposition. The measurement that causes the collapse of the wave function eliminates this uncertainty revealing the state of the system. The collapse occurs as the result of an experiment or observation. It is the discovery of the state of the system. The process of discovery—revelation—in the terminology of Kabbalah—is the process of revealing Alma d’Isgalya (Revealed World) from Alma d’Iskasya (Hidden World). This is why the splitting of the sea can be seen as an allegory of the collapse of the wave function.

Egyptian Exile as a Metaphor for Compactification in String Theory

And they made their lives bitter with hard service, in mortar and in brick…Exodus 1:14 On a literal level, the Egyptian exile (Galut Mitzrayim) is a story of the Jewish people’s enslavement in ancient Egypt, where they were forced to do hard labor making mortar and bricks, and building cities for the Pharaoh. On a deeper level, it is axiomatic in Jewish mysticism that suffering is usually a means to purify and rectify a sinner’s soul in this or past incarnation. It is also axiomatic that any sin damages the sinner’s soul and some supernal spiritual levels that obstruct the flow of the divine benefice into the world, impeding the blessing and, therefore, causing suffering to the sinner. Technically, it works as follows. When a sin committed below causes damage above, the resulting [...]

Jacob in a State of Superposition

And when Jacob made an end of charging his sons, he gathered up his feet into the bed, and expired, and was gathered unto his people. And Joseph fell upon his father’s face, and wept upon him, and kissed him. And Joseph commanded his servants the physicians to embalm his father. And the physicians embalmed Israel. . . . And his sons carried him into the land of Canaan, and buried him in the cave of the field of Machpelah, which Abraham bought with the field, for a possession of a burying-place, of Ephron the Hittite, in front of Mamre. (Genesis 49:33–50:13)Rabbi Yitzchak said to Rav Nachman: “So said Rabbi Yochanan: Our father Jacob did not die.” Asked Rav Nachman: “Was it for no reason that the eulogizers eulogized, the embalmers embalmed and [...]

Joseph’s Birth—A View From Quantum Mechanics and Biology

And afterwards she bore a daughter, and called her name Dinah. (Genesis 30:21) In my previous essay, “The Conflict Between Joseph And His Brothers—A Gender Theory,” I suggested that Joseph exhibited some proclivity to feminine behavior in his youth. This impression can be naturally inferred from the verses and supported by traditions in Kabbalah related to Isaac, Joseph, and Benjamin, as we discussed in that essay. To be sure, Joseph outgrew his feminine tendencies (perhaps assisted by the tough love shown to him by his brothers). He matured into a man who was not only a husband, a father, and the de facto ruler of Egypt, but an archetype of masculinity and a paradigm of piety, for which he earned the designation of Joseph, the Righteous (Yosef HaTzadik). Moreover, spiritually, Joseph personified Yesod [...]

The Conflict Between Joseph And His Brothers—A Gender Theory

The confrontation between Joseph and his brothers is one of the most troubling stories of the Bible. Joseph and his brother—twelve sons of Jacob—were the progenitors of the twelve tribes of Israel. They are described as tzadikim (the righteous and pious men) and prophets. However, as we read in the Torah portion Vayeshev, we are told that brothers hated Joseph: And when his brethren saw that their father loved him more than all his brethren, they hated him, and could not speak peaceably unto him. (Genesis 37:3) And Joseph dreamed a dream, and he told it to his brethren; and they hated him yet the more. (Genesis 37:5) And his brethren envied him… (Genesis 37:11) The brothers intended to kill Joseph: And they said one to another: ‘Behold, this dreamer cometh. Come now [...]

Jacob’s Struggle With a Man: A Metaphor From Neuroscience

So the present passed over before him; and he himself lodged that night in the camp. And he rose up that night, and took his two wives, and his two handmaids, and his eleven children, and passed over the ford of the Jabbok. And he took them, and sent them over the stream, and sent over that which he had. And Jacob was left alone; and there wrestled a man with him until the breaking of the day. And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob’s thigh was strained, as he wrestled with him. And he said: “Let me go, for the day breaketh.” (Genesis 32:23–26)   The story of Jacob wrestling with a “man” is yet another of [...]

On Rachel, Leah, and Dark Energy

Now Laban had two daughters: the name of the elder was Leah, and the name of the younger was Rachel. (Genesis 29:16)   Rabbi Isaiah Horowitz (the Shelah HaKadosh)[1] famously says that the Torah speaks to the upper words and hints to the lower words. That means that the primary subject to the Torah narrative has to do with the dynamics of the spiritual worlds while only hinting at the historical narrative that appears to be the meaning of the biblical text. It is not surprising because what happens down here reflects what happens up there—in the spiritual spheres. However, the historical narrative is not necessarily the only reflection of the higher reality. We may see how the same or similar dynamic is reflected in natural laws. This Torah portion introduces us to two [...]
