By Baladeva Vidyabhusana
King Sawai Jai Singh II (1688-1743 AD) commissioned Sri Baladeva Vidyabhu?a?a (c.1700-1793 AD) to compose a Gau?iya commentary on the Brahma-sutra. In response, Sri Vidyabhu?a?a first presented the Brahma-sutra-karika-bha?ya in a very condensed format, and years later, the Govinda-bha?ya, a much more extensive and elaborate work. In order to duly facilitate the comprehension of the latter, he subsequently composed the Siddhanta-ratna, a dense treatise covering major philosophical and theological topics. Being requested by his students, he further penned the Prameya-ratnavali, a Vedanta-prakara?a in which he succinctly focused on the objects of knowledge or theorems (prameya) dealt with in Vai??ava philosophy.
