wrote another commentary named Ratna-prabha.  Vacaspati Mis’ra, who flourished about 841 A.D., wrote another commentary on it called the Bhamati. Amalananda (1247—­1260 A.D.) wrote his Kalpataru on it, and Apyayadik@sita (1550 A.D.) son of Ra@ngarajadhvarindra of Kanci wrote his Kalpataruparimala on the Kalpataru. Another disciple of S’a@nkara, Padmapada, also called Sanandana, wrote a commentary on it known as Pancapadika.  From the manner in which the book is begun one would expect that it was to be a running commentary on the whole of S’a@nkara’s bhasya, but it ends abruptly at the end of the fourth sutra.  Madhava (1350), in his S’a@nkaravijaya, recites an interesting story about it.  He says that Sures’vara received S’a@nkara’s permission to write a varttika on the bhasya.  But other pupils objected to S’a@nkara that since Sures’vara was formerly a great Mima@msist (Ma@n@dana Misra was called Sures’vara after his conversion to Vedantism) he was not competent to write

a good varttika on the bha@sya.  Sures’vara, disappointed, wrote a treatise called Nai@skarmyasiddhi. Padmapada wrote a @tika but this was burnt in his uncle’s house.  S’a@nkara, who had once seen it, recited it from memory and Padmapada wrote it down.  Prakas’atman (1200) wrote a commentary on Padmapada’s Pancapadika known as Pancapadikavivara@na. Akha@n@dananda wrote his Tattvadipana, and the famous N@rsi@mhas’rama Muni (1500) wrote his Vivara@nabhavaprakas’ika on it.  Amalananda and Vidyasagara also wrote commentaries on Pancapadika, named Pancapadikadarpa@na and Pancapadika@tika respectively, but the Pancapadikavivara@na had by far the greatest reputation.  Vidyara@nya who is generally identified by some with Madhava (1350) wrote his famous work Vivara@naprameyasa@mgraha [Footnote ref 1], elaborating the ideas of Pancapadikavivara@na; Vidyara@nya wrote also another excellent work named Jivanmuktiviveka on the Vedanta doctrine of emancipation.  Sures’vara’s (800 A.D.) excellent work Nai@skarmyasiddhi is probably the earliest independent treatise on S’a@nkara’s philosophy as expressed in his bha@sya.  It has been commented upon by Jnanottama Mis’ra.  Vidyara@nya also wrote another work of great merit known as Pancadas’i, which is a very popular and illuminating treatise in verse on Vedanta.  Another important work written in verse on the main teachings of S’a@nkara’s bha@sya is Sa@mk@sepas’ariraka, written by Sarvajnatma Muni (900 A.D.).  This has also been commented upon by Ramatirtha.  S’rihar@sa (1190 A.D.) wrote his Kha@n@danakha@n@dakhadya, the most celebrated work on the Vedanta dialectic.  Citsukha, who probably flourished shortly after S’rihar@sa, wrote a commentary on it, and also wrote an independent work on Vedanta dialectic known as Tattvadipika which has also a commentary called Nayanaprasadini
