Author's Preface - Page 2

I take this opportunity of expressing my gratitude to Professor
James H. Woods, of Harvard University, for his generous
appreciation which encouraged me to complete this series of
papers and read most of them before the Harvard University. And
I offer my thanks to Mr. Ernest Rhys for his kindness in helping
me with suggestions and revisions, and in going through the
proofs.

A word may be added about the pronouncing of Sadhana: the accent
falls decisively on the first a, which has the broad sound of the
letter.
