This book is a portrait of a music master who attained spiritual realization through music and who could guide his students and listeners along the music path or mârg sangît, revealing its beauty and its depth to them. Ustad Zia Mohiuddin Dagar’s music was a teaching in itself and it needed no words to convey a message; it reflected equanimity and it was enriched by peace and wisdom. This book is about the nature of Dhrupad, the oldest and most refined genre of Indian classical music. This book is about Dhrupad music as yoga in all the meanings of the word. It is also about the living tradition of “guru-shishya-paramparâ” that is to say the relation between a master and his students and the direct transmission of knowledge. This book resonates with the voices of students, musicians, music lovers and admirers of Ustâd Zia Mohiuddin Dagar, who sing his praise in unison.
