While working on the adaptation, Marie-Hélène Estienne travelled across Nepal and India, journeying from Manipur to Kanchipuram, in order to learn of the many different forms of the ancient epic from “Brahmins and writers and dancers and theatre people” across the subcontinent. Music composer Toshi Tsuchitori remained in India for months on request from Brook make sure the play would "not use the music which everybody knows". Musicians from Iran, Turkey, and Denmark joined the production in order to score musical elements discovered by Tsuchitori, who was particularly influenced by Rabindra Sangeet.
