the present volume, his interest in the progress of my work has
been untiring. Page by page, and stanza by stanza, he has re-
viewed the work with me. No details have been too small to
gain his notice, no problems too trifling to enlist his help. He
has always been patient, always encouraging. His advice and
suggestion have always been freely mine even during his busiest
times. Never could a pupil have had a better guru, and if it is
true, as of course it is, that the guru is reflected in the work of his
pupil, then whatever is good in this volume is his.
