The Principal Upanishads by Dr S Radhakrishnan

The Principal Upanishads is a 1953 book by Sarvepalli Radhakrishnan (1888–1975). It contains an extended introduction, romanized Sanskrit texts, English translations, and commentary on the main Upanishads, which Radhakrishnan presents as carrying the central teachings of the Vedanta. For readers who want one substantial English volume that frames these texts through a single scholar’s interpretation, it remains one of the most widely known editions. This guide explains what the book contains, how it is organized, where its interpretation should be read as Radhakrishnan’s own, and how to approach it alongside other sources.

What The Principal Upanishads Is

The book is an edition and translation, not a summary. Its largest portion, roughly pages 147 to 938 according to the catalog description summarized on Wikipedia, presents Sanskrit originals in romanized transliteration rather than Devanagari, followed by verse-by-verse translation and commentary. Readers who expect a short popular overview will find a long academic-style volume instead.

The Upanishads themselves are a body of texts that Hindu tradition treats as part of the Vedic corpus, usually understood as the concluding portions of the Vedas and often called Vedanta. The word Upanishad is commonly rendered as “sitting near” or “close sitting,” a reference to teacher and student. Radhakrishnan’s introduction discusses the term directly under the heading “The Term ‘Upaniṣad’,” so readers can check his reasoning in the book itself.

Who Wrote It and When

Sarvepalli Radhakrishnan was a philosopher and scholar who later served as the second President of India. Wikipedia describes him as Vice President of India when the book appeared. The book was first published in 1953 by Harper, and the author’s preface is dated 1951, which means the translation and commentary were prepared before the published date. Later editions were issued by other publishers, including Allen & Unwin in the United Kingdom and Harper India.

Across editions, the page count has been reported as 958, and the title has remained the same. The spelling of “Upanishads” has varied. You may see Upaniṣads, Upanisads, or the retroflex “sh” written as “ṣ” or “ṣh” in catalog listings. These are transliteration differences, not different books. If you search library or bookstore catalogs, try several spellings.

Editions you may encounter

• The 1953 Harper edition, the original publication, which the author’s preface and publication history place in the early 1950s.
• Later reprints, including a 1994 edition cited by Wikipedia, which share the same title and page count according to that article.
• Digitized copies on the Internet Archive, including an entry listing Radhakrishnan as editor and translator, and a Digital Library of India record of the same title.
• Retail listings under ISBN 81-7223-124-5 and the 9781722312459 listing, which appear on commercial sites. Check the publisher and page count before buying, since listings can be inconsistent.

How the Book Is Organized

The introduction

The book opens with a 129-page introduction. According to the outline summarized on Wikipedia, it is divided into 19 sections. Reading the section headings together shows the sequence of Radhakrishnan’s argument:

• General influence, the term “Upaniṣad,” and questions of number, date, and authorship.
• The relation of the Upanishads to the Vedas: the Ṛg Veda, the Yajur, Sāma, and Atharva Vedas, the Brāhmaṇas, and the Āraṇyakas.
• The Upanishads as the Vedanta.
• Ultimate reality: Brahman, and ultimate reality: Ātman, followed by “Brahman as Ātman.”
• The status of the world and the doctrines of Māyā and Avidyā.
• The individual self, knowledge and ignorance, and ethics.
• Karma and rebirth, life eternal, and religion.

These headings show that the introduction moves from historical and textual questions toward philosophical and ethical ones. Readers who want background on the Vedas before the Upanishads will find it in the early sections.

The translated texts

After the introduction, the book presents eighteen Upanishads in this order: Bṛhadāraṇyaka, Chāndogya, Aitareya, Taittirīya, Īśa, Kena, Kaṭha, Praśna, Muṇḍaka, Māṇḍūkya, Śvetāśvatara, Kauṣītāki, Maitrāyaṇi, Subāla, Jābāla, Paiṅgala, Kaivalya, and Vajrasūcikā. Wikipedia gives this list, and it matches the order of the book’s contents as summarized there.

The sequence matters less than the method. Each text is given in Sanskrit transliteration, then translated verse by verse, then discussed in commentary. This arrangement lets a reader compare the Sanskrit wording with the English rendering, which is useful for students who want to check specific terms.

Appendices and bibliography

The book includes two appendices on the perspectives of Rabindranath Tagore and Edmond Holmes on the Upanishads. It also has a selected bibliography of about two pages and a general index of about six pages. Those features make it usable as a reference, not only as a continuous read.

The Core Themes Radhakrishnan Emphasizes

The section headings point to several themes that Radhakrishnan treats as central. It is important to read these as his presentation of the Upanishads within Vedanta, not as a neutral summary that every reader or tradition would accept.

Brahman and Ātman

Two headings, “Ultimate Reality: Brahman” and “Ultimate Reality: Ātman,” are followed by “Brahman as Ātman.” The relationship between the cosmic reality called Brahman and the inner self called Ātman is a major topic in many Upanishadic passages. Radhakrishnan’s section title signals that he takes the identity of these two as a key teaching. Readers should note that Vedanta schools have understood this identity in different ways, and that the book is an interpretation of the texts, not the only possible reading.

Māyā, Avidyā, and the status of the world

The introduction includes a section on “The Status of the World and the Doctrine of Māyā and Avidyā.” Māyā and Avidyā are later Vedanta vocabulary, and their precise use varies among schools. Radhakrishnan’s heading shows that he connects these terms with the Upanishadic account of the world. A careful reader should separate what the Upanishadic passage says, what Radhakrishnan says it means, and what later commentators added.

Karma, rebirth, and liberation

The later headings “Karma and Rebirth” and “Life Eternal” show that the book also addresses ethical and soteriological questions. Karma and rebirth appear in many Indian traditions, not only in the Upanishads, and their formulation differs across Hindu, Buddhist, and Jain thought. When reading this part of the book, identify whether a statement comes from the Upanishadic text, from Radhakrishnan’s commentary, or from the broader tradition he is explaining.

Practical reading rule: when a page moves from Sanskrit text to translation to commentary, note which layer you are reading. The book is most useful when those layers are kept separate.

Scripture, Tradition, and Scholarship: Keeping the Layers Apart

Readers often ask whether a particular teaching is “what the Upanishads say.” The honest answer depends on the layer. Radhakrishnan’s book helps show these distinctions when read carefully.

• Scripture: the Sanskrit text of each Upanishad, which the book reproduces in romanized form.
• Translation: Radhakrishnan’s English rendering. A translation always involves choices about terms such as Brahman, Ātman, and Māyā, so a single word may appear differently in other editions.
• Commentary: Radhakrishnan’s explanations, which reflect his own philosophical framing.
• Tradition: the ways that Vedanta schools, sampradayas, and devotional communities have read these texts over centuries. Many traditions do not read the Upanishads identically.
• Modern scholarship: historical work on dating, authorship, and the development of the texts. Radhakrishnan’s introduction discusses number, date, and authorship, but scholars continue to debate these questions, and later research should be consulted.

Treating the book as one interpreter’s careful presentation, rather than a final statement of Hindu belief, helps readers avoid claiming more than the texts or the sources support. Hindu practice is diverse, and many devotees approach the Upanishads through worship, recitation, and teacher guidance rather than through a single academic edition.

Why the Count of “Principal” Upanishads Varies

The title says principal, but the word does not refer to a single fixed list. Radhakrishnan’s book translates eighteen texts, a larger set than many readers expect when they hear “the principal Upanishads.” Other lists, including traditional and modern groupings, select a smaller number, and some readers count ten, twelve, or thirteen. The Wikipedia summary of the book notes that the main Upanishads carry the central teachings of the Vedanta, but it does not supply a single definitive count that all traditions accept.

If you are trying to decide which texts to read first, compare the lists rather than assuming one number applies everywhere. HindusGod has related explanations of the ten principal Upanishads, the thirteen principal Upanishads, and the ten principal Upanishads in a different treatment. A more complete discussion of the thirteen-text grouping appears in The Thirteen Principal Upanishads. Where lists differ, the difference usually reflects a choice about which texts count as principal, not a dispute about whether the Upanishads exist.

Reading the Book Step by Step

Because the volume is long, a structured approach helps. The following order works for many readers who want to understand both the text and the interpretation.

1. Read the introduction’s headings first. Note how the 19 sections move from history and terminology to philosophy and ethics.
2. Read one short Upanishad in full. The Īśa, Kena, Kaṭha, and Māṇḍūkya are relatively brief in many editions, so they are often used as starting points. Check the length in your edition before deciding.
3. Compare the translation with the Sanskrit. Even without Sanskrit fluency, you can see how a term is transliterated and note the translator’s rendering.
4. Mark where commentary begins. Keep a separate note of Radhakrishnan’s interpretation so you can return to the text itself.
5. Check a second translation or commentary. Comparing editions shows where interpretation affects meaning.

A reader who follows this order will spend more time with the texts and less time with the summary, which is the most common way that a dense edition like this becomes manageable.

An example of layered reading

Suppose you are studying the theme of Brahman and Ātman. Begin with the introduction sections titled “Ultimate Reality: Brahman,” “Ultimate Reality: Ātman,” and “Brahman as Ātman.” Then locate the Upanishadic passages Radhakrishnan cites in the relevant translated text. Finally, compare his commentary with the translated passage. In your notes, record three things separately: what the Sanskrit text says, what Radhakrishnan’s English translation says, and what his commentary adds. This keeps scripture, translation, and interpretation distinct.

Limits and Cautions

The book is valuable, but it has limits that a responsible reader should know.

• Date of composition. The book was published in 1953. Translation and scholarship have changed since then, so compare it with newer academic translations where possible.
• Interpretive stance. The commentary reflects Radhakrishnan’s philosophical perspective. Other scholars and traditions read the same texts differently.
• Reception. Wikipedia includes a reception section, but the portion available to this draft did not provide enough detail to summarize reviewers’ views responsibly. Consult the reception section directly or a reliable review before making claims about how the book was received.
• Unofficial copies. User-uploaded copies on document-sharing sites may not be authorized. One Scribd listing of the book carries a Creative Commons non-commercial label, but the uploader’s rights claim should not be assumed to be valid. Prefer a library, the Internet Archive record, or a licensed publisher edition.

Where This Book Fits in a Study Plan

The Principal Upanishads is a reference-length work, so it works best after a shorter introduction. Readers new to Upanishadic literature may first want the general overview and then the separate posts on individual texts.

Frequently Asked Questions

Is The Principal Upanishads a translation or a commentary?

It is both. The book reproduces the Sanskrit texts in romanized transliteration, gives an English translation of each verse, and adds commentary. Keeping those three layers separate is the best way to read it.

Which Upanishads does Radhakrishnan include?

The book includes eighteen texts, from the Bṛhadāraṇyaka and Chāndogya at the start to the Vajrasūcikā at the end. The full list is given in the section above, drawn from the Wikipedia summary of the book’s contents.

Why are there different spellings in catalogs?

Sanskrit words are transliterated into English in several systems. The retroflex “sh” may appear as “ṣ,” “ṣh,” or “sh,” and “Upanishads” may be written with or without the diacritics. The title and page count have stayed the same across the editions summarized here, so search with several spellings.

Takeaway

The Principal Upanishads by S. Radhakrishnan is a substantial introduction to eighteen Upanishadic texts, presented through the scholar’s own introduction and commentary. It is most useful when readers separate the Sanskrit text, the translation, the commentary, the wider tradition, and modern scholarship. Use it as a serious reference, check it against other editions, and treat its interpretations as one informed reading rather than the only account of the Upanishads.
