A Word-Level Digital Reader of the Prasthanatrayi with Sankara's Bhasya

An open, offline, word-level digital reader and annotated language resource for the Prasthanatrayi — the ten principal Upanisads, the Brahmasutra, and the Bhagavadgita — together with Sankara's complete commentary (bhasya), the foundational corpus of Advaita Vedanta. Every word of both the root text (mula) and the commentary is annotated with its euphonic split (padaccheda), morphological/syntactic analysis, and English gloss, and is clickable in the reader; because every word is lemma-tagged, the reader also serves as a concordance searchable by dictionary head-word or by English meaning. The resource covers 13 commentarial units (2,971 root-text units; 36,881 analysed word-occurrences) and a dictionary of 95,587 distinct analysed commentary surface forms. The deposit contains the self-contained HTML readers, the reusable JSON data, the build and evaluation pipeline, and the accompanying paper. Built with deterministic Sanskrit resources plus LLM-assisted analysis under an adversarial verification protocol and a human expert-review loop; see README.md and ATTRIBUTIONS.md.
