"Rāginī" (Devanagari: रागिनी) is a term for the "feminine" counterpart of a "masculine" rāga. These are envisioned to parallel the god-goddess themes in Hinduism, and described variously by different medieval Indian music scholars. For example, the "Sangita-darpana" text of 15th-century Damodara Misra proposes six "rāgas" with thirty "ragini", creating a system of thirty six, a system that became popular in Rajasthan. In the north Himalayan regions such as Himachal Pradesh, the music scholars such as 16th century Mesakarna expanded this system to include eight descendants to each "rāga", thereby creating a system of eighty four. After the 16th-century, the system expanded still further.
