PREFACE. xxi Nyayalankara, who was the crest jewel of the Pundits of Bengal; that he wrote a commentary on a work by Budhavara i.e., the author of the text, Nandarama. The other commentary is also on Nandarama Tarkavagica's work. It relates to the knowledge of spiritual truth, and is not confined to Vedanta system alone.
