The present work, and especially the learned notes which its editor has supplied at its end, will give the reader an interesting idea of this contact of mind with mind and thought with thought that was going on for nearly five centuries from c. 500 to 1,000 A.D. The contact was by no means purely acrimonious, but it helped the development of logic and philosophy. There is a general belief in modern times that commentators merely explain the original texts and do not make any contributions of their own. This is not entirely true. The development of the Hindu Law is largely due to the medieval commentators and the Mitakshara has almost entirely eclipsed the Yajnavalkyasmriti in the modern law courts.

This is undoubtedly a pleasing feature of Hindu scholarship. Had it obtained a wider scope, India would have had greater intellectual advance and achievements to her credit. The K. P. Jayaswal Research Institute is thankful to Sri. Dalsukhbhai Malvania of the College of Oriental Learning, Hindu University, Banaras, for undertaking the editing and publication of this work. He has spared no pains in making it as flawless as possible. He has utilised two unpublished MSS of Nyayabindutika and given at the end references to other works where we have related passages to elucidate the view-points in the Dharmottarapradipa. His Introduction gives a learned account of the history of logic from the days of the Buddha to the end of the 11th century A.D. It is
