a medical text called Patanjalatantra. He is cited and this text is quoted in many medieval health sciences-related texts, and Patanjali is called a medical authority in a number of Sanskrit texts such as Yogaratnakara, Yogaratnasamuccaya and Padarthavijnana. There is a fourth Hindu scholar also named Patanjali, who likely lived in 8th-century CE and wrote a commentary on Charaka Samhita and this text is called Carakavarttika. According to some modern era Indian scholars such as P.V. Sharma, the two medical scholars named Patanjali may be the same person, but completely different person from the Patanjali who wrote the Sanskrit grammar classic Mahābhashya. Patanjali is one of the 18 siddhars in the Tamil siddha (Shaiva) tradition. Patanjali continues to be honoured with invocations and shrines in some forms of modern postural yoga, such as Iyengar Yoga and Ashtānga Vinyāsa Yoga. Name According to Monier Monier-Williams, the word "Patañjali" is a compound name from "patta" (Sanskrit: पत, "falling, flying") and "añj" (अञ्ज्, "honor, celebrate, beautiful") or "añjali" (अञ्जलि, "reverence, joining palms of the hand"). Life Many scholars including Louis Renou have suggested that the Patañjali who wrote on Yoga was a different person than the Patanjali who wrote a commentary on Panini's grammar. In 1914, James Wood proposed that they were the same person. In 1922, Surendranath Dasgupta presented a series of arguments to tentatively propose that the famed Grammar text and the Yoga text author may be identical. The view that these were likely two different authors is generally accepted, but some Western scholars consider them as a single entity. Some in the Indian tradition have held that one Patañjali wrote treatises on grammar, medicine and yoga. This has been memorialised in a verse by Bhoja at the start of his commentary on the Yogasutras called Rājamārttanda (11th century), and the following verse found in Shivarama's 18th-century text: This tradition is discussed by Meulenbeld who traces this "relatively late" idea back to Bhoja (11th century), who was perhaps influenced by a verse by Bhartṛhari (ca. 5th century) that speaks of an expert in yoga, medicine and grammar who, however, is not named. No known Sanskrit text prior to the 10th century states that the one and the same Patanjali was behind all the three treatises. The sage Patañjali is said to have attained Samadhi through yogic meditation at the Brahmapureeswarar Temple located at Tirupattur, Tamil Nadu, India. Jeeva Samadhi of sage
