A guide to the four Vedas

Four streams of knowledge

The Vedas are collections of hymns, ritual formulas and chants, and other sacred material. These cards introduce each tradition and show only the Upanishads currently on this shelf. The labels are traditional affiliations, not claims about a manuscript's historical school.

Guide: Encyclopaedia Britannica, Veda ↗. Artwork is original CSS illustration, not a scanned manuscript.

About the manuscripts and this edition

Handle these pages with care

The source is a 3,580-page scan of the 108 Upanishads with Upanishad Brahmayogin's commentary. The Veda and Muktika numbers follow a traditional list and do not prove a specific historical shakha. English introductions paraphrase the texts; they are not translations of the commentary.

These CSVs are derived from OCR and checked in stages, not a critical edition. Sanskrit OCR may still have errors; please compare important readings with the source scan ↗. Unfinished texts are not listed as finished.

A note on the five provisional texts - a small number of datasets, marked with a vermillion ribbon, carry heavier OCR damage (Yogashikha's opening chapter most of all). They are shared openly as working drafts, with their limits written on each cover, so scholars can use them with eyes open.
