INTRODUCTION xxxix Acknowledgements Thankful acknowledgements are due to the authorities of the Kerala University Manuscripts Library for lending the two MSS. used for this edition. I express my sincere gratitude to Prof. A. A. Ramanathan who has not only seen the whole work through the press but also made many useful suggestions. He has also helped to provide the sources of quotation in the sutra-s. I am grateful to Prof. K. Kunjunni Raja who has always shown keen interest in my work. I thank the German Research Council for the grants which enabled me to travel to the places like Gokarna where I could discuss with traditional Pandits and clarify certain obscure portions of the text.
