________________ INTRODUCTION The late Dr. J. S. Jetly had undertaken an ambitious project as early as in 1970. The project was to prepare a critical edition of (1) Padarthadharmasangraha (PDS) of Sri Prasastapada, with (2) Nyayakandali (NK) of Sri Sridharacarya-a commentary on the former, supplemented with three commentaries on NK.-viz. (3) Nyayakandali-Tippana by Naracandrasuri (4) Panjika by Rajasekharasuri and (5) Kusumodgama by Sidila. Out of these five, the printed editions of the first two were available. Dr. Jetly, however used some more manuscripts for collation and thus prepared a fresh text of these two treatises. The remaining three commentaries were unpublished. Dr. Jetly found out MSS. of all these three from different Bhandaras and started to prepare their respective texts. He had already completed the collation of Tippana and Panjika and gave me the rough copies of these two edited texts for preparing a press-copy. He then started editing Kusumodgama. Unfortunately, he succumbed to a massive heart attack and passed away in 1972, leaving this work unfinished. His untimely and unexpected sad demise brought a halt to his last cherished project for sometime. However, Dr. B. J. Sandesara, the then Director of Oriental Institute, M. S. University of Baroda, expressed his desire to see the project completed, as it was already accepted by the Institute for publication. Mrs. Sureshaben Jetly kindly gave me the incomplete copy of the edited text of Kusumodgama along with the original Manuscript of the same. With the blessings of Mrs. Jetly and warm encouragement from Dr. Sandesara, I could complete the editing of the remaining part of Kusumodgama and also the press-copy of the whole work. Dr. Arunoday Jani, who was the Director of Oriental Institute at that time, showed a keen interest in this treatise and accepted it for publication. However due to some circumstances, the work could not go to the press. It was Dr. Sureshchandra Kantawala, the Director of Oriental Institute, who took an active interest in the project and asked me to rearrange the order of the commentaries and the original text, so as to suit the format of the printing device. This being done, the work' actually went to the press. Afterwards, Dr. R. T. Vyas, the present Director of Oriental Institute, took special care for the continuous printing of this work. It is his sincere effort and deep love for the research that has made this publication possible. It is sad that Dr. Jetly could not live to see his project completed.
