In 1966,The Mother asked Sunil Bhattacharya to compose the musical accompaniment for Her readings of Sri Aurobindo’s Savitri. He continued to compose music for Savitri (and for the New Year) till his passing in 1998.
In his compositions for Savitri and for the New Year, Sunilda incorporated chantings of mantras from the Vedas, the Upanishads and various Stavas and Stotras, invoking the diverse Godheads of India. To him, the Mother and Sri Aurobindo were the Supreme as well as all the Goddesses and Gods of Indian mythology. As a result, we often find him replacing the names of the different deities mentioned in the originals with the names of the Mother or Sri Aurobindo.

The Fire with his high flaming up-pillared, sublime, the firmament and became the highest of the luminous kingdoms (Or, highest of all lights), when for the flame-seers life, that grows in the mother, kindled all around the carrier of the offerings who was hidden in the Secrecy.

O Fire, achieve at my call the Revealing Speech the many-actioned, the lasting conquest of the Light. May there be for us a Son of our begetting pervading in his birth (Or, himself a begetter) ; O Fire, may there be created in us that true thinking of thine.
