Pātañjalayogadarśanam

The title designates a unified work, not a collection of independent texts. Philipp Maas's research demonstrated that the Yoga Sutras and the commentary traditionally ascribed to 'Vyāsa' were composed by a single author, Patañjali, as an integrated treatise . Before Maas, scholars had generally assumed the bhāṣya was written centuries later by a different figure, and many tried to read the sutras alone, treating the commentary as a later and possibly distorting addition . The single-authorship thesis, first proposed by Johannes Bronkhorst in 1985, means that the bhāṣya is Patañjali's own explanation of his own aphorisms—the best available evidence for how the Yoga Sutras were meant to be understood .

The work is dated to approximately 400 CE. This is established through two textual reference points. First, Pātañjalayogadarśanam 4.16 shows familiarity with the works of the Buddhist philosopher Vasubandhu, who lived between 320 and 400 CE . Second, the text is quoted in the Nyāyabhāṣya of Vātsyāyana, composed around 450 CE, and in the oldest commentary on Bhartṛhari's Vākyapadīya, whose author flourished between 450 and 510 CE . Maas has placed the argument for 325–425 CE on firmer footing than earlier scholarship, though the narrower window around 400 CE is now generally accepted . This dating rules out the traditional claim that Patañjali was a contemporary of Pāṇini or lived centuries before the Common Era.

The attribution of the bhāṣya to Vyāsa—a mythical or semi-divine figure—was not the original position of the tradition. Maas showed that every scholar in ancient and medieval India up to about 1000 CE took single authorship as self-evident; the idea of two separate authors gained ground only in later centuries . The tenth-century commentator Vācaspatimiśra appears to have originated the distinction, and his authority shaped subsequent readings . Even then, his attitude was ambiguous, and early commentaries such as the Vivaraṇa treat sutra and bhāṣya as a single treatise . The 'Vyāsa' attribution is thus a later scholarly construction, not a continuous tradition, and it obscures the text's original unity.

Yes. Pradeep Gokhale has criticized the single-authorship hypothesis on doctrinal grounds, arguing that single authorship could only be accepted if there is uniformity of thought between the sutras and the commentary, and identifying cases where the bhāṣya deviates from what the sutra says or implies . Maas has responded to this challenge by reexamining the alleged incompatibilities and questioning Gokhale's basic assumptions about what uniformity of thought requires . The debate remains active, and readers should be aware that while the single-authorship thesis is now the dominant scholarly position, it is not universally accepted. The evidence is cumulative and text-immanent rather than a single decisive proof.

Modern editions of the 'Yoga Sutras' often present only the aphorisms, sometimes with a translation of the bhāṣya appended as a separate commentary. This format inverts the original structure. Pātañjalayogadarśanam is a single work in which the bhāṣya carries much of the doctrinal content: the eight limbs, the afflictions (kleśas), the siddhis, and the polemic against rival schools are elaborated in the prose commentary, not in the terse sutras . Reading the sutras alone, without the bhāṣya, is like reading a table of contents without the chapters. The Yoga Sutras as a standalone text is a modern construction; Pātañjalayogadarśanam is the form in which Patañjali's philosophy was actually composed and transmitted.

The oldest preserved and most informative commentary is the Pātañjalayogaśāstravivaraṇa by an author named Śaṅkara, possibly from the eighth century, though whether this is the Advaita philosopher of the same name remains unresolved . Vācaspatimiśra's Tattvavaiśāradī (c. 950 CE) became highly influential but has been criticized for frequently failing to provide first-hand explanations of a text from an ascetic milieu alien to its author . King Bhoja's Rājamārtaṇḍa (early eleventh century) took the innovative step of extracting the sutras and providing a paraphrase of the bhāṣya with his own explanations . Vijñānabhikṣu's Yogavārttika (late sixteenth century) offers a Bhedābhedavedānta reading, though it is often indebted to Vācaspatimiśra .
