The Vedāntasāra of Sadānanda (17th century A. D.) is a well-known primary text-book of Advaita Vedānta, popular among the students of Vedānta. Out of the three Sanskrit commentaries on it available now in print, the Vidvanmanorañjani of Rāmatīrtha is also the one. Nothing is known about him except that he was a disciple of Svāmi Kṛṣṇatīrtha. He might have lived during the 17th century A. D. His commentary is simple and lucid.
