I. Necesrity of a Critical word-Index.
It was as early as December 1931 that I had felt the necessity of an exhaustive word-index to the Bhagavadigita because I had to deliver a presidential address at a Gita-jayanti celebration at Bulsar where I then was and intended to speak therein on the repeated emphasis laid in that work on the relation between life and philosophy. I had felt the same necessity over again when in 1933 I drafted my Introduction to the critical edition of the Siddhantabiody published as No. 64 of the Gaekwad's Oriental Series, wherein I had traced the history of the Advaita doctrine from the Vedic times to the time of the author, the 17th century A. D. On none of those occasions, however, had I any idea as to the amount of necessity for the same felt by other students of the work. Nor did I then feel the urge to make an attempt to undertake that work myself because unless one feels that there is a chance of one's work being appreciated by those for whom it is meant one does not think it worth his while to take it up. Such an urge came upon me only when in Dr. V. S. Sukhtankar's review of the verse-Index of that work published by Dr. W. Kife) of the University of Bonn' I found a hope expressed that some Indian scholars will wake up to the necessity of preparing at long last a complete index verborum f this crest-jewel of Indian literaturean index in which every occurrence of every infected and uninflected word and every grammatical form will be separately indexed and cited as in Grassmann's Woritarbuch to it Rgछ€ia' ’. It was impressed on my mind again and with greater force when I read in Prof. R. D. Laddu's review of Arthur C. March's work entitled ‘A Buddhist Bibliography ", the prefatory remark that the importance of a complete bibliography on a subject or an inder शerborum to a work can hardly be over-estimated by any one interested in the pursuit of research. The rapid growth that has been taking place in the literature relating to comparative philology, philosophy and religion to-day necessarily demands of a researchist complete upto. date bibliographies on his subjects as well as the serbora to the works within the purview of his study. Where there are none of the kind he has to compile them himself for his own use, which is, no doubt, a giddy task that takes away so much of his energy ". I, therefore,
