555) Resisting the friendship impulse: Relationships in the teachings of Ishbitz

Introduction

This article—based extensively on the research by Professor Israel Koren—explores a most unusual approach to sociability, friendship and family, in the teachings R. Mordechai Yosef Leiner of Izbica (Ishbitz) (1800-1854). He dramatically broke away from the warm, traditional Chassidic conception of interpersonal relationships, which had previously been regarded positively as both reflective of, and parallel to, union with the Divine. Instead, he promoted a decidedly anti-social stance where sociability was scorned. Today, the Ishbitzer’s work, Mei haShiloach, is very popular. However, R. Mordechai’s striking ambivalence toward human friendship and companionship goes mostly unnoticed. Koren’s study of the Isbitzer’s distinct asociality contributes to a fuller understanding of the writings of Ishbitz. 

554) Rabbinic perspectives on honour killings

The Bat Rabim collection of manuscripts in the Russian State Library.

Introduction

This article—based extensively on the research by Dr Moti Benmelech—examines rabbinic perspectives on honour killings. It traces the fraught process by which some rabbis tried to reconcile local honour codes with Jewish law and practice, while others resisted and pushed back to deliberately limit its reach to uphold Jewish legal and moral standards. 

Honour Killings

An honour killing, or shame killing, typically refers to the murder of a female family member by a male relative, who believes she has behaved immorally, committed adultery, or otherwise brought shame upon the family. Such killings are intended to preserve or restore the family’s perceived honour and reputation. The phenomenon persists to this day, and according to the UN, five thousand girls and women are killed each year in honour‑related violence. 

553) The forgotten legacy of Philo of Alexandria

 Introduction

This article—based extensively on the research by Rabbi Dovid Campbell—examines the often-overlooked intellectual legacy and deep influence of Philo Judaeus of Alexandria (20 BCE-50 CE) on later Jewish thought. Philo, a leader of “the largest Jewish community of the first century,” may have been “one of history’s most influential Jews”. He laid solid foundations for “the entire stream of Western philosophy, including its religious and distinctively Jewish branches” (Campbell 2024:42). Essentially, Philo was an early, if not the first, thinker to understand the Torah as speaking the language of philosophy behind the plain meaning of its text. For Philo, Torah was philosophy. At this stage in Jewish history, Torah meant Tanach or Bible, because the rabbinic or Talmudic period was just beginning. Philo introduced numerous philosophical ideas into Judaism that changed its shape forever, but the man behind these contributions was lost to Jewish history. Today, we only know about Philo because other religious traditions preserved his work. In fact, many of his forgotten contributions have unknowingly become part of the very fabric of contemporary Orthodox Judaism, to the extent that those who disregard them would—to this day—almost certainly be considered as espousing heretical views. Campbell’s groundbreaking research expounds on this peculiar irony. 

552) The added blessing in the Amidah: Who are we cursing?

 

Kefar Sachnin in Galilee

Introduction:

This article—based extensively on the research by Professor R. Reuven Kimelman[1]—examines the twelfth of the eighteen (today nineteen) blessings of the Amidah, in an attempt to establish just who it is referring to. The nature of the ‘blessing’ is more of a curse and a petition for this community (or these communities) to “instantly perish.” The text of this prayer—which is today known as Bircat haMinim (Blessing denouncing the Heretics)—becomes a fascinating window into Jewish perceptions of the need to exclude the ‘other’ during the first century CE. The question is: who is this unnamed ‘other’ (or ‘others’)? 

551) R. Joseph Ber Soloveitchik’s adaptation of German Volk elements.

Introduction

This article—based extensively on the research by Professor Daniel Herskowitz[1]—examines how certain elements of Germanic Volkish (volk = folk) thought, circulating in interwar Germany, are evident in the writings of R. Yosef Ber Soloveitchik, also known as the Rav (1903-1993). Volkism was a folk, cultural, and ideological movement which began in Germany in the late 19th century. R. Soloveitchik studied cultural themes that also appeared in Volkish and later National Socialist discourse, but R. Soloveitchik’s use was philosophical, not political. To be clear, although R. Soloveitchik adopted Volkish thought, he severely criticised it when it became politicised, adopted and weaponised by the Nazi party in Germany in the 1930s. Nevertheless, Volkism did indeed become the basis of the National Socialist movement in Germany. 

550) Likutei Halachot: Reinterpreting Halacha as a means to connect with the Tzadik

My copy of Likutei Halachot by R. Natan Sternhartz

Introduction

This article—drawing extensively on the research by Dr Leore Sachs-Shmueli[1]—examines the nineteenth-century Chassidic work, Likutei Halachot, by R. Natan Sternhartz of Nemirov (1780-1844). R. Natan worked on his manuscript of Likutei Halachot for forty years, from 1806 to two days before his passing in 1844. His autograph (i.e., original) manuscript is housed in the  National Library of Israel. This work by R. Natan, the foremost student of R. Nachman of Breslov (1772-1810), essentially redefines Halachic practice as a mnemonic (memory system) and theurgic (spiritually manipulative) means of connecting with the Tzadik, R. Nachman of Breslov (or more accurately Bratslav).

549) From Serafim to Sefirot: The Kedusha and the rise of human participation in the cosmic drama

The Kedusha in a 1745 Siddur according to the custom of the Arizal

Introduction

This article—drawing extensively on the research by Dr Leore Sachs-Shmueli—examines a fundamental shift in the mystical interpretation of the Kedusha, recited during the communal repetition of the Amidah (standing prayer). The Kedusha, with its liturgy dating to the fifth century CE (Fleischer 1998:305), was understood in early Jewish mysticism—particularly the Heichalot and Merkavah literature beginning from around the second century CE—as an opportunity for earthly worshippers to imitate and mimic the prayers of the heavenly angels who united heaven and earth through their recital of the Kedusha. In this ancient framework, human prayer was conceived as an echo of the primary celestial liturgy. However, with the emergence of the Zoharic corpus in the late thirteenth century (the Zohar first circulated around 1290), a significant theological shift took place. The angels, who were once conceptualised as being central to the Kedusha, were now relegated to the margins, while humanity assumed the pivotal role in a cosmic drama that sought to unite heaven and earth. 

 

548) Early Mussar: Demonic threat management and displacement of the Divine

Yiddish translation of Kav haYashar

Introduction

In a previous article, we delved into the possibility of Sabbatian connections to, if not outright authorship of an early Mussar (ethical) text, the  Kav haYashar [see: Kotzk Blog: 303) MYSTICAL YIDDISH TEXTS AS A CONDUIT FOR CHASSIDIC THOUGHT:]. This article—drawing extensively on the research by Professor Isaac Hershkowitz—explores a different dimension of the Kav haYashar with its striking emphasis on angelology and demonology. These themes are not incidental but central to the work, to the point where they appear to eclipse God in the text’s pursuit and development of religious-ethical development (Mussar). In early Mussar, such as Kav haYashar, ethical conduct is shaped more by obedience to a cosmic system of angels and demons. In this scheme, God is to a notable degree marginalised—eclipsed, displaced, if not altogether absent—from the process of moral perfection. Likewise, the individual’s own self-effort is detached from the work of ethical refinement. Instead, early Mussar emphasises the conceptual struggle of enlisting good angels and combating demonic forces as the primary path toward moral righteousness. 

547) From the Nile to Safed: Egyptian Judeo-Sufism as an influence on Lurianic Kabbalah

Introduction

This article—drawing extensively on research by Professor Paul Fenton—expands upon the previous discussion of six generations (Fenton 2025-)[1] of Maimonides’ Egyptian descendants who embraced and disseminated a synthesis of Jewish mysticism and Islamic Sufism, known as Judeo-Sufism. This movement, with large numbers of adherents known as Chassidim, followed a mystical path called Derech haChasidut (Fenton 2017:50). Its influence eventually reached Safed, transmitting Judeo-Sufi ideas and practices that arguably informed the Arizal’s sixteenth‑century Lurianic Kabbalah. 

546) Jewish Mystics and Rationalists seeking Islamic Fatwas during the Maimonidean Conflicts

 Introduction

This article seeks to explore how thirteenth-century Jews often sought Fatwas (religious edicts) from Islamic courts to intervene during the intense period of Maimonidean Conflicts. These Conflicts—also known as the Maimonidean Controversies—erupted after Maimonides’ passing in 1204, and were more like Jewish civil wars between the Maimonidean rationalists and the emerging mystics, with the Zohar first published eighty-six years later in 1290, in Christian Spain. The mystical opponents of Maimonides were often backed by Christian authorities such as the Dominicans, Franciscans and even King James I of Aragon [see: Kotzk Blog: 263) THE POLITICS BEHIND THE PIETY - BRINGING THE BATTLE INTO THE SIDDUR:]. 

545) Psychedelics: Cutting-edge science or shamanic ritual?

Homological scaffolds of the brain before and after psilocybin (Petri G., et al. 2014).

Part II

Introduction

This article builds on the previous discussion, which explored how psychedelics are increasingly being framed as “cutting-edge science,” embraced by “all the professors”—and, most troubling in my view, promoted as a new expression of Jewish mysticism and experientialism [Kotzk Blog: 544) Acculturating Alcohol and Sanctifying Psychedelics: It’s time to stand up]. While this article departs from the usual style of discourse on this platform, a recent encounter prompted me to dig deeper. After hearing an average, conservative, middle-aged man explain that he was about to embark on an ayahuasca journey because of its “proven scientific value” and its common use among “trusted religious people” in his community, I decided to examine the academic literature on psychedelics more closely. I aimed to assess how solid the claim of a scientific foundation truly is. In the interest of fairness, I have included scholarly arguments both for and against the use of psychedelics. 

544) Acculturating Alcohol and Sanctifying Psychedelics: It’s time to stand up

Part I

Introduction

Alcohol and drug abuse have long been perceived as problems external to the Jewish religious community. Currently, however, the rising visibility of alcohol consumption alongside drug and psychedelic practices, is closer to home than we may have imagined. According to psychologist Dan Wolf,^[1] the difficulty lies in the fact that, whereas in the past, a range of methodologies were actively employed to counter alcohol and substance abuse, the prevailing attitude seems to be that quiet and moderate use is perhaps the most reasonable approach. Today, the issue of substances and psychedelics is no longer abstract or distant; it is reshaping the very fabric of our communal life, demanding recognition, response and a solid stance.
