the six beautiful photos adorning the book. My esteemed

friend Sri K. Raghupati Rao of Dasaprakash 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 jignåsus will offer
āsūs 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 ।
