This is a unique rhetorical work in Sanskrit literature, quoted by such eminent authors as Mammaṭa-Bhaṭṭa. In point of singular outspokenness, fearless criticism, and utter disregard of contemporary opinion, few rhetoricians can compare with Mahima-Bhaṭṭa. He wrote his wellknown work at a time when the critical spirit was at the highest pitch, and his courageous exposure of the prevailing schools of thought and his daring attempt to set up an original school in their stead are commendable. Though often referred to by later authors and quoted piecemeal, the Vyakti-vivēka, as a whole, has till now remained a sealed book to the public at large. A paper manuscript of the work that was available to me, as well as the Mysore Oriental Library copy to which I had access through the courtesy of the Curator, supplied the materials for this brief sketch.
