The comparison available in Vedanta Atlas covers three traditions, Advaita (Śaṅkara), Viśiṣṭādvaita (Rāmānuja) and Dvaita (Madhva), drawn from four English translations. The Sanskrit of each sūtra comes from a separate printed edition for each tradition, credited under Sanskrit texts below.
Why these translators, and why these editions
Three of the four editions are English translations by George Thibaut, published in the Sacred Books of the East series. The Madhva commentary is the 1904 Madras translation by S. Subba Rau, the complete public-domain English rendering of that text. This is a starting point, not a statement that either translator is the only or final authority on any of these texts; it reflects which faithful, public-domain translations were available to extract and structurally verify first. Additional editions and translators can be added alongside these in the future without disturbing the records already built.
Being in the public domain matters here for a practical reason: it allows the full source text to be preserved, extracted, and checked against the original pages without restriction, which is central to this project’s evidence-first approach.
How a source becomes readable, comparable data
Each edition passes through several distinct layers before it appears in the Atlas. The source is the original text itself, kept unmodified. The structural layer records where each sūtra begins and ends and what commentary follows it, without adding interpretation. The shared numbering gives every sūtra a stable reference number that other editions can align against. The alignment layer records how one edition’s sūtras correspond to another’s; see How Vedanta Atlas Works for what those correspondence labels mean and how uncertain cases are reviewed.
The shared numbering and alignment layers are still provisional and under active review.
