Sureà Âvara (also known as Sureà ÂvarÃÂcÃÂrya, was a 9th-century Indian philosopher, who studied under à Âankara. à Âankara is said to have entrusted to Sureà Âvara his first monastic institution, the Sringeri Sharada Peetham. Sureà Âvara is believed to have founded the Naduvil Matham in Thrissur. His Maha Samadhi is located near the Sharada temple of Sringeri Mutt in Sringeri Karnataka.
Little is known for sure about Sureà Âvara's life. According to a persistent but erroneous tradition within Advaita VedÃÂnta, before he became a disciple of à Âankara, Sureà Âvara was known as Maá¹Âá¸Âana Mià Âra, a MëmÃÂmsÃÂka. After being defeated in a debate by à Âankara, Mià Âra renounced his life as a householder and became a sannyÃÂsin. Whether this Maá¹Âá¸Âana Mià Âra was the same as the author of Brahmasiddhi is questioned by modern scholars on the basis of textual analysis.
Sureà Âvara was the Advaita tradition's VÃÂrttikakÃÂra (commentator), meticulously and critically examining à Âankara's work. In his non-commentary work, the Naiá¹£karmyasiddhi, he presents Avdaita philosophy clearly and simply.
Maá¹Âá¸Âana Mià Âra has often been identified with Sureà Âvara. Sureà Âvara (fl. 800âÂÂ900 CE) and Maá¹Âá¸Âana Mià Âra were contemporaries of à Âankara. Both explained à Âankara "on the basis of their personal convictions."
According to Kuppuswami Sastri, it is not likely that Maá¹Âá¸Âana Mià Âra, the author of Brahmasiddhi, is identical with Sureà Âvara, but the tradition is correct in describing Maá¹Âá¸Âana Mià Âra and à Âankara as contemporaries. His critical edition of the Brahmasiddhi also points out that the name Maá¹Âá¸Âana Mià Âra is both a title and a first name, which is a possible cause for a confusion of personalities. Maá¹Âá¸Âana Mià Âra's brand of Advaita differs in certain critical details from that of à Âhankara, whereas Sureà Âvara's thought is very faithful to that of à Âankara.
According to Sharma, Hiriyanna and Kuppuswami Sastra have pointed out that Sureà Âvara and Maá¹Âá¸Âana Mià Âra had different views on various doctrinal points:
R. Balasubramanian disagrees with the arguments of Kuppuswami Sastri and others, and argued that there is no conclusive evidence available to prove that Maá¹Âá¸Âana, the author of the Brahmasiddhi, is different from Sureà Âvara, the author of the Naiá¹£karmyasiddhi and the VÃÂrtikas.
