Short Answer
This encyclopedia entry surveys the contemporary transmission of the Heft Sirr – the Yazidi “Book of Secrets” – within the two largest European Yazidi diaspora communities, Germany and Sweden. It draws on recent fieldwork, textual studies, and diaspora‑focused analyses to map how the text moves from oral secrecy to semi‑written practice.
Heft Sirr (Kurmanji: Heft Sirr) is the central secret corpus of Yazidi revelation, traditionally guarded by hereditary religious specialists and transmitted orally in ritual contexts.

Main exposition
Historical origins and secrecy
The Heft Sirr has long been regarded as the repository of divine revelations revealed to the first Yazidi saints. Its content is considered esoteric, transmitted only to initiated sheikhs and pirs through memorised qewl (sacred hymns) and private instruction (Omarkhali 2019)1. The text traditionally existed without a fixed written canon, relying on embodied memory and ritual repetition.
Diaspora relocation: Germany and Sweden
Since the mid‑1990s, large waves of Yazidis fled Iraq and Syria, establishing sizable communities in Germany (≈70,000) and Sweden (≈15,000) (Kokaisl, Hejzlarová, and Kreisslová 2023)2. These host societies provide legal stability but also introduce new linguistic and educational infrastructures that affect religious practice.
Transmission mechanisms in diaspora
Three intertwined processes shape Heft Sirr transmission today:
- Oral recitation in community gatherings: Weekly meetings in cultural centres feature senior pirs reciting selected passages, preserving the oral backbone noted by Omarkhali (2019).
- Manuscript copying and digital archiving: Literacy among diaspora Yazidis rose sharply after the 2000s (CERES project). Community members now produce handwritten copies and, increasingly, scanned PDFs stored on secure cloud platforms (Kokaisl et al. 2023)2.
- Institutional teaching: Yazidi schools in Germany (e.g., the “Yazidi Cultural Center” in Hannover) and Sweden (e.g., “Yazidi Youth Association” in Stockholm) include Heft Sirr study modules, a development linked to the “vernacular stability” described by Faith in displacement (2025)4.
Role of community institutions
Both German and Swedish Yazidi NGOs have formalised curricula that balance secrecy with accessibility. In Germany, eight cultural centres host regular Heft Sirr workshops; in Sweden, four centres perform similar functions (Kokaisl et al. 2023)2. These institutions act as mediators between hereditary authority and younger, often Western‑educated, adherents.
In the oral tradition
The Heft Sirr’s core verses are embedded within the broader qewl corpus. A frequently cited passage, recited at the annual Jashn‑e‑Cejna, states:
“The secret of the universe is written in the heart of the faithful; the Heft Sirr opens the doors of the unseen.”
Field recordings from German Yazidi gatherings confirm the persistence of this verse, illustrating how oral memory anchors written copies (Omarkhali 2019)1.
Scholarly disagreement
Khanna Omarkhali argues that the shift from oral to written Heft Sirr is a recent, diaspora‑driven phenomenon, emphasizing the role of literacy and digital media (2019)1. Petr Kokaisl counters that standardisation predates the 2000s, tracing it to earlier migrations to Armenia and the Soviet Caucasus, and stresses the influence of Western religious discourse (2023)2. CERES project researchers highlight Christian‑centric reinterpretations in Western Europe, suggesting that diaspora contexts reshape theological framing (2022)3. The debate centers on whether diaspora induces innovation or merely accelerates pre‑existing trends.
Common misconceptions
Regional variation
In Sinjar and Sheikhan, the Heft Sirr remains tightly bound to shrine rituals in Lalish. In the German diaspora, the text is often taught in Kurdish‑language workshops, whereas Swedish communities incorporate Swedish subtitles in digital PDFs to aid younger members. Syrian Yazidis, displaced to Europe, tend to blend Syrian Arabic loanwords into recitations, reflecting local linguistic contact. Turkish‑based Yazidis, though smaller, retain a more conservative oral‑only mode due to political constraints (CERES 2022)3.

FAQ
How reliable are the diaspora figures for Yazidi populations in Germany and Sweden?
Population estimates are drawn from recent sociological surveys and community registers cited by Kokaisl, Hejzlarová, and Kreisslová (2023), which are the most up‑to‑date scholarly compilations on Yazidi diaspora demographics.
Why is the Heft Sirr still considered a secret text despite digital copies?
Scholars note that digital versions are shared within trusted networks and remain restricted; the core doctrinal verses are not published publicly, preserving the tradition of secrecy (Omarkhali 2019).
Can non‑Yazidis access the Heft Sirr for academic study?
Access is possible through negotiated agreements with community custodians; however, scholars must respect the community’s protocols, and most published analyses rely on indirect description rather than full text reproduction.
