By Baladeva Vidyabhusana
King Sawai Jai Singh II (1688-1743 AD) commissioned Śrī Baladeva Vidyābhūṣaṇa (c.1700-1793 AD) to compose a Gauḍīya commentary on the Brahma-sūtra. In response, Śrī Vidyābhūṣaṇa first presented the Brahma-sūtra-kārikā-bhāṣya in a very condensed format, and years later, the Govinda-bhāṣya, a much more extensive and elaborate work. In order to duly facilitate the comprehension of the latter, he subsequently composed the Siddhānta-ratna, a dense treatise covering major philosophical and theological topics. Being requested by his students, he further penned the Prameya-ratnāvalī, a Vedānta-prakaraṇa in which he succinctly focused on the objects of knowledge or theorems (prameya) dealt with in Vaiṣṇava philosophy.
