The pleasant task remains to thank those persons and institutions that have assisted me in many different ways. I am deeply indebted to the Governments of India and of the Netherlands. Both (the former through its Reciprocal Scholarships Scheme) enabled me to live and study in India for three years. I hope that this book will give some idea of my Indian experiences, which have been a constant source of inspiration ever since.
I am greatly indebted to the University of Madras for having permitted me to work in the University and to submit the thesis upon which the present work is based.
My gratitude goes in the first place to my teacher and guide, Dr. T.M.P. Mahadevan, Professor of Philosophy and Head of the Department of Philosophy of the University of Madras. He helped me in every conceivable way. He not only taught me the doctrines of Advaita, but showed me by his example how an Advaitin thinks and lives.
It is a pleasant duty to acknowledge my debt to Dr. V. Raghavan, Professor of Sanskrit and Head of the Department of Sanskrit of the University of Madras, whom I often approached with questions and who always supplied me immediately and unhesitatingly with a wealth of information and references.
I should also like to thank Mr. S. Sankarasubrahmanya Ayyar, B.A., of the Kuppuswami Sastri Research Institute, Mylapore, who with great enthusiasm and perseverance acquainted me both with the principles of Sanskrit and with the techniques of Pāṇini.
It is a privilege to be able to express my gratitude to His Holiness Abhinava Vidyā Tīrtha Svāmigal, present Śaṅkarācārya of the Śṛṅgeri Maṭha, for his kindness and interest in my work. By living in his proximity and by speaking with him I came to understand more than texts could provide.
I should have liked to thank personally my first teacher in philosophy, Dr. H.J. Pos, Professor of Philosophy in the University of Amsterdam. His personal interest in my work and his brilliant expositions of Greek thought from Thales to Plotinus were very much alive in my mind when I received in India the announcement of his unexpected death.
