The reign of Mughal emperor of India Akbar the Great was more than four centuries ago, but for Dances of India President Nartana Premachandra, the story of his court — and its welcoming of all nationalities, religions and perspectives — is as salient as ever. She shares some of that history in her original dance-theater production, “Nine Jewels: Music, Art, & Splendor in the Court of Akbar the Great,” which takes the stage this weekend as part of Dances of India’s 48th annual performance.
