the six beautiful photos adorning the book. My esteemed
friend Sri K. Raghupati Rao of Dasaprakaāsaprakāsh who has been
a source of encouragement to me deserves special mention.
 
My thanks are also due to my colleague Sri G. V. S. S.
Sarma, M. A., who went through the Sanskrit proofs
and offered useful suggestions. I am also thankful to
Sri H. S. Guru Rao who cheerfully undertook to supervise
the printing of this book in Madras and helped me
in many other ways. My hearty and profound thanks
are no less due to the authorities of Rathnam Press who
have always kept up their high standard of printing and
who executed this work with their usual care and neatness
I now send forth this book into the world with the hope
that the learned readers as well as the jignāsūs will offer
their valuable and useful suggestions and point out defects-
all of which will be attended to while preparing the next
edition of this book. I conclude this introduction with the
following prayer of the ācārya :
 
अशेषकल्याणगुणनित्यानुभवसत्तनुः ।
अशेषदोषरहितः प्रीयतां पुरुषोत्तमः ।
