This book is a multi-faceted study of the Sros Dron, comprising chapters 3 to 8 of the Yasna ceremony, the core ritual of the Zoroastrian religion. It provides a critical edition produced with the electronic tools of the project The Multimedia Yasna, and a study of the performative aspects of the Sros Dron both through the lens of the ritual directions and in comparison with the Dron Yast ceremony. By analysing the Sros Dron both as a text attested in manuscripts and as a ritual performance, Celine Redard applies a new approach to unlock the meaning of these chapters of the Yasna.

This edition gives a transcription of Anklesaria's text, an English translation, a Gujarati-English glossary, an introduction to Gujarati-language works on ritual directions and a study on the relationship between Anklesaria's text and the liturgical manuscripts in Yasna 3-8. Unlocking the meaning and performative aspects in this first-ever edition in any European language, of these core Zoroastrian rituals in India, Celine Redard and Kerman Dadi Daruwalla open up the Indian tradition for future research and highlight its importance.
