that Patañjali learned Yoga along with seven other disciples from the great Yogic Guru Nandhi Deva, as stated in Tirumular's Tirumandiram (Tantra 1). His Samadhi is said to be at Rameswaram Shiva temple and a shrine for him still exists in the temple.

Works Whether the two works, the Yoga Sutras and the Mahābhāṣya, are by the same author has been the subject of considerable debate. The authorship of the two is first attributed to the same person in Bhojadeva's Rajamartanda, a relatively late (10th century) commentary on the Yoga Sutras, as well as several subsequent texts. As for the texts themselves, the Yoga Sutra iii.44 cites a sutra as that from Patanjali by name, but this line itself is not from the Mahābhāṣya. This 10th-century legend of single-authorship is doubtful. The literary styles and contents of the Yogasūtras and the Mahābhāṣya are entirely different, and the only work on medicine attributed to Patañjali is lost. Sources of doubt include the lack of cross-references between the texts, and no mutual awareness of each other, unlike other cases of multiple works by (later) Sanskrit authors. Also, some elements in the Yoga Sutras may date from as late as the 4th century C.E., but such changes may be due to divergent authorship, or due to later additions which are not atypical in the oral tradition. Most scholars refer to both works as "by Patanjali", without meaning that they are by the same author. In addition to the Mahābhāṣya and Yoga Sūtras, the 11th-century commentary on Charaka by the Bengali scholar Chakrapani Datta, and the 16th-century text Patanjalicarita ascribes to Patañjali a medical text called the Carakapratisaṃskṛtaḥ (now lost) which is apparently a revision (pratisaṃskṛtaḥ) of the medical treatise by Caraka. While there is a short treatise on yoga in the medical work called the Carakasaṃhitā (by Caraka), towards the end of the chapter called śārīrasthāna, it is notable for not bearing much resemblance to the Yoga Sūtras, and in fact presents a form of eightfold yoga that is completely different from that laid out by Patañjali in the Yoga Sūtras and the commentary Yogasūtrabhāṣya.
