Sukkah: the Portal into the Holy Land

Sukkah: the portal into the Holy Land Sitting with my wife in our sukkah-hut recently, I was struck by a memory from some four decades ago. During Chol HaMoed Sukkot, I visited my mentor and friend, Rabbi Benzion Feldman. I shared with him that, while sitting in our sukkah, my wife and I had discussed the possibility of making Aliyah to Israel. Rabbi Feldman smiled and said, “The reason you and your wife were thinking about Israel while sitting in your sukkah is that the air in the sukkah is the air of Eretz Yisrael.” Indeed, Eretz Yisrael is under constant divine watchfulness, as it says: A land which the Lord your G-d cares for; the eyes of the Lord your G-d are always upon it. (Deuteronomy 11:12) The sukkah also symbolizes G‑d's protection [...]

Bet HaMikdash as a Singularity in Space-time

Bet HaMikdash as a Singularity in Space-time

Introduction In this essay, I intend to draw a parallel between the singularity in space-time, such as the putative point of origin of the universe in the Big Bang cosmology, on the one hand, and the Jerusalem Temple (Bet HaMikdash) as it existed on the terrestrial plane before its destruction and as it continues to exist on the celestial plane—in the four spiritual worlds of the Universe of Tikkun. Another unexpected parallel between the cosmological singularity and the Bet HaMikdash as the embodiment of ten sefirot (divine emanations) is that in cosmology and in Lurianic Kabbalah they both play the role of a “wormhole”—a channel connecting different universes. As a brief introduction, Lurianic Kabbalah is a school of Jewish mysticism developed by Rabbi Isaac Luria (1534-1572), also known as the Holly Ari or [...]

Physics of Tzimtzum I — The Quantum Leap

Physics of Tzimtzum I — The Quantum Leap

Introduction “In the beginning G‑d created the heavens and the earth.” (Genesis 1:1) “In the beginning G‑d created the heavens and the earth,” the Torah says. However, what was before the “beginning”? It is like asking, What was before the Big Bang? In physics, until relatively recently, such questions were discouraged. The prevailing wisdom was that time and space had been created by the Big Bang, and there was no “before” before the Big Bang. Mishnah discourages such thinking, too. The sages point out that the first letter of the Torah, the letter bet, is open on the left and closed on the right:[1] The text of the Torah and the history of the world proceed from that opening on the left. The closed right side of the letter bet visually walls off [...]

Black Holes and Gravitational Waves

A hole in Kabbalah is called “rah” (evil). The reason for that is, as content is lost due to a leakage through the hole, forces of evil get their nourishment from leakage of light. Kabbalah views the world as divided into two domains – a domain of holiness (“sitrah d’kedushah”) and a domain of evil, so-called "the other side" (sitrah acharah). A hole is viewed as a portal from the domain of holiness into the other side – the domain of evil. This is why, for example, we are commanded to attach mezuzot to the doors of our houses. Doors viewed as portals of evil, through which good energy of the house can leak into the outside – the domain of evil. The mezuzah containing the affirmation of the oneness of G‑d, plugs these [...]
