## About Longchenpa

**Longchenpa** (Tib. *Klong chen rab 'byams pa*, 龙钦绕绛, 1308–1364) was a preeminent scholar and accomplished master of the Nyingma tradition during China's Yuan Dynasty. Revered as the "Omniscient Dharmakāya of Luminous Primordial Purity" (*Kun mkhyen Chos sku 'Od gsal rnam dag*), he is celebrated for:

- **Systematizing Dzogchen teachings**: Authoring the foundational *Seven Treasuries* (*mDzod bdun*) and *Trilogy of Natural Freedom* (*Rang grol skor gsum*)
- **Integrating scholarship and practice**: Combining rigorous philosophical analysis with profound meditative insight
- **Revitalizing Nyingma transmission**: Preserving and transmitting the earliest Tibetan Buddhist tantric lineages

Longchenpa's writings profoundly influenced all subsequent Tibetan Buddhist schools, particularly through his synthesis of Madhyamaka philosophy and Dzogchen practice. He was also an early and enthusiastic reader of the newly compiled Tibetan Buddhist Canon (*Kangyur* and *Tengyur*), frequently citing canonical sources in his works.

## Dataset Scope and Structure

### **Source Edition**

This translation project is based on the **Beijing *Snar thang* edition of Longchenpa's collected works (26 volumes)**, the most modern and comprehensive publicly available compilation. It includes:

- **All non-ritual Dzogchen and Vajrayāna treatises**
- **Major Mahāyāna philosophical works**
- **Poetic compositions and practice manuals**

**Source data**: Directly derived from the digitized text published by **tsadra.org**, ensuring reproducibility and accessibility.

---

### **Translation Coverage**

**Historical Context**: 
- Approximately **75% of Longchenpa's writings have never been translated into Chinese or other languages**
- This project marks the **first complete translation of a major pre-modern Buddhist master's entire corpus** alongside frequently cited canonical sources into a widely accessible language

**Version 4.0 Enhancements**:
- **Multiple AI model translations** for cross-validation:
  1. **Claude 3.0 - 3.7 Sonnet** (Anthropic): Primary translation (highest quality)
  2. **GPT-4o** (OpenAI): Supplementary translation
  3. **Gemini 2.0** (Google DeepMind): Additional version for comparison
  
- **Four Chinese translations** for major treatises (enabling textual criticism)
- **Comprehensive English translations** (newly added in v4.0)
- **26-volume structured corpus** (~4-5 million characters)

### **AI Models and Quality Assurance**

**Translation Approach**:
- **Tibetan → Modern Chinese**: Leveraging linguistic proximity (both derive from Sarvāstivāda scholastic traditions, sharing technical terminology)
- **Tibetan → English**: Direct translation (avoiding intermediary languages)
- **Cross-model validation**: Multiple AI outputs compared to identify and resolve ambiguities

**Quality Control**:
- **Automated segmentation**: Sentence-level alignment with original Tibetan
- **Human oversight**: Editorial review for critical philosophical terms
- **Note on errors**: As stated in project documentation, AI translations may contain inaccuracies. Users are advised to:
  - Consult original Tibetan texts for scholarly work
  - Compare multiple translation versions
  - Exercise critical judgment

**Technical Notes**:
- Files marked `c3.7s`: Claude 3.7 Sonnet (automatic, with overlapping validation sentences at segment boundaries)
- Files marked `C3.7S`: Claude 3.7 Sonnet (manual processing)
- Files marked `g2.0`: Gemini 2.0 (automatic)
- Files marked `gpt4o`: GPT-4o (automatic)

## Important Disclaimers

### **Reader Responsibility**

As stated in the project documentation:

In the G2.0 translation edition (volumes 1, 2, 3, 5, 6, 7, 8, 11, 12, etc.) produced between July and November 2025, approximately 1% (a very small proportion) of the text contains entire paragraphs that were accidentally omitted in translation.To address this issue, we have written a dedicated program to perform electronic collation and supplementary translation. As of November 26, 2025, this remedial work has not yet been fully completed.Under normal circumstances, the upgraded complete volumes will first be released at:
https://huggingface.co/datasets/ospx1u/buddhist-classics-vol1-12/tree/main  and subsequently published on zenodo.org.
Other data repositories will be updated on a case-by-case basis or may not be updated at all.
