The first of the three Jewish Holidays of pilgrimage , Sheloshim Regalim, which starts the annual Holiday cycle

## Passover Seder—The Arrow of Time

The Passover Seder has four main parts: Kiddush (sanctification), Magid (telling the story of the Exodus), Shulchan Orech (the festive meal), and Nirtzah (Hallel—the prayer for the Messianic redemption). This sequence sets the natural arrow of time past-present-future. Past. During the Magid part of the seder, we retell the story of the Exodus of the Jewish people from Egypt—the narrative of the history of Jewish people. Eating of the matzah, drinking four cups of wine and other "simonim" of the Seder table—bitter herbs, an egg, a bone, charoset, etc.—are all symbols that have historical significance. This part of the Seder clearly represents the past. Present. During the Shulchan Orech part of the Seder, we participate in the festive meal. We eat. One cannot eat in the past or the future—one can only eat [...]

## Pesach Sheini – in a State of Superposition

In physics, we speak of systems and states. A system is a collection of physical objects (particles, waves, etc.). A system can be in various states. For example, a coin could have two states – heads and tails. A top also has two possible states – it can be spinning clockwise or counterclockwise. Light can have two states as well – being in the vertical polarization or horizontal polarization. In classical mechanics a system can only be in a pure state, i.e., at any given point in time, a coin can be either in a state “Heads” or the alternative state “Tales”. A top can be spinning either clockwise or counterclockwise, each of which is a pure state. In quantum mechanics, a system can be in a pure state or in a state [...]

## 613 Degrees of Freedom

Passover has ended.  All Jews hastily remove their Passover dishes into special cabinets or the attic until next Passover.  After an eight-day break, home becomes filled with the aroma of freshly baked bread.  Passover leaves us with the pleasant taste of burnt matzot, memories of the Seder spent with family, and stories of the Exodus.  But did Passover really end? In the Mishnah (the precursor of Talmud), the holiday of Shavuot (Pentecost) is called “Atzeret.”  This word is familiar to us from Shemini Atzeret—the holiday that follows immediately after the seven days of Sukkot, often simply viewed as the last day (or, in Diaspora, the last two days) of Sukkot.  Either way, Shemini Atzeret is the conclusion of the festival of Sukkot.  By designating Shavuot as Atzeret, the Mishnah seems to imply that it is [...]

## Four Cups and Three Matzoth

On Seder night we drink four cups of wine and eat three matzoth. Why four cups and not three? Why three matzoth and not four? The same numerical relationship exists among our forefathers. We have the patriarchs – Avraham (Abraham), Yitzchak (Isaac) and Yaakov (Jacob). But we have four matriarchs – Sarah, Rivkah (Rebeca) Rachel, and Leah. This dynamics also manifests itself in the holiest name of God – Tetragrammaton – YHWH. Why does the four-letter Name have only three unique letters, Yud, Heh, and Vav? According to Sefer Yetzirah – a classic text of Kabbalah attributed to Abraham or to Rabbi Akiva – there are three letters of Hebrew Alef Bet called mothers: Alef, Mem, and Shin, which are considered to be “primary” letters. The three mothers represent the basic logical triad [...]

## From Purim to Passover

The Shulchan Aruch – the Code of Jewish Law – states that 30 days before Pesach (Passover) one needs to start learning the laws of Pesach. The simple meaning of this directive is clear – the laws are many and complicated and there is a lot to learn – so one needs to start early. There may be a deeper meaning in this, however. Let us recall that Pesach and Purim are exactly 30 days apart. To start learning about Pesach 30 days before, means to start learning about Pesach on Purim. Or, perhaps, the message is that from Purim we can learn about Pesach. The word Purim means “lot.” The story of Purim is about throwing lots. Evil Haman threw one lot to choose a month for the pogrom against Jews of [...]

## Pesach – Time of our Freedom

The holiday of Passover – Pesach – is called zman cheruteinu– time of our freedom. As we have discussed many times on this blog (see Interpreting Dreams; It’s the time, stupid! Carpe Diem; Mezuzah and Time; Riddle — the answer; Splitting the Sea), freedom can only be obtained by mastering time. Everything about celebrating Passover is related to time. It all starts on the Rosh Chodesh Nissan (the New Moon, the beginning of the month of Nissan – marked by the renewal of the monthly lunar cycle – during which we celebrate Passover).  On that day, the very first commandment was given to the Jewish people – the commandment to set the calendar by the lunar cycle, i.e., the commandment of keeping time. Classical commentators ask: Why the Torah (which means “Instruction”) does not have as [...]

## Carpe Diem

As we have discussed in the post, It’s the time, stupid, Pharaoh never got the message that it’s all about mastery of time.  To make sure Jews did get this message, God gave them the very first commandment—the commandment of keeping time, of marking new months:           This month shall be unto you the beginning of months; it shall be the first month of the year to you.(Ex. 12: 2) It is important to note that Jews were not only commanded to keep time, they were commanded to “make” time.  Indeed, in Biblical times, the new month was not calculated according to a calendar, as it is done today, it was proclaimed by a Bet Din (an ecclesiastic court) based on the testimony of two live witnesses, who observed [...]

## Paradox of the Red Heifer

Chukat In the previous post, Tumah and Taharah, we discussed the following ideas: Tumah (impurity) and taharah (purity) are strictly spiritual concepts; Spiritual concepts are points in a conceptual space, which is called in mathematics a "fiber bundle" on the fifth "moral" dimension defined in Sefer Yetzira (in addition to four dimensions of spacetime); Tumah and taharah are mirror reflections of each other as if tumah was an "antiparticle" of taharah; Life is viewed as the soul's existence within the body, and, conversely, the soul's separation from the body causes cessation of life; Tumah is usually associated with death or diminution of life. The wisest of all man, King Salomon, could not fathom the paradox of Parah Adumah (the Red Heifer): Why does the person who administers the ritual of purification become tomei (spiritually impure) himself? It [...]

## Freedom in Space, Time and Spirituality

And the entire Mount Sinai smoked because the Lord had descended upon it in fire, and its smoke ascended like the smoke of the kiln… Exodus 19:18 The Holiday of Shavuot is thought to be a culmination of the Passover. Just as Shmini Atzeret is a culmination of the Holiday of Sukkot and comes after seven days of Sukkot, Shavuot is also called Atzeret and comes after the Holiday of Pesach, albeit separated from it by forty-nine days of Omer. On Shavuot we read a Torah portion from the Chapter 19 of the Book of Shemot (Exodus). We already discussed the verse 18, "Mount Sinai smoked," in the previous post, Mount Sinai smoked because the Lord had descended upon it. Here, I'd like to focus on the word "smoked" from a different perspective. [...]

## Passover, Shabbat and the Principle of Least Action

There is hardly a Jewish holiday more widely celebrated than Passover (Pesach). Jews of all denominations, affiliations, and levels of religious observance—if any at all—gather at the Passover Seder to tell the story of the Exodus from Egypt. What is often lost amid all of the beautiful rituals, not least among them the singing of Had Gadia and other Seder songs, is the deep meaning of this holiday, which is far more profound than a mere recollection of historical events, no matter how important they may be. What is, then, the deeper meaning of Pesach that transcends its historical significance? On the morrow of Shabbat One obscure and little-known (outside of the observant Jewish community) mitzvah may lead us to a deeper understanding of the meaning of Pesach – this is the commandment [...]
