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.
MANTRAS IN SUNILDA'S SAVITRI MUSIC
BOOK 01 CANTO 02
भद्रं ते अग्ने सहसिन्ननीकमुपाक आ रोचते सूर्यस्य ।
रुशद् दृशे ददृशे नक्तया चिदरूक्षितं दृश आ रूपे अन्नम॥१॥
Happy is that flame-power of thine, O forceful Fire ; it shines close to the Sun, glowing to vision it is seen even in the night, it is as if in its beauty (or, in its form) there were an unarid feast for the eye.
O Fire, O thou with thy many births even as we hymn thee force open the heavens (or, the door or entrance) with thy quivering lustre (or, with thy lustre of knowledge) for him who utters the mind of wisdom ; O Brilliant, O glorious Flame, what thou with all the gods hast won, that give to us, that mighty thought.
O Fire, from thee are born the seer-wisdoms, from thee the mind of knowledge, from thee the utterances that achieve ; from thee come the riches that take the hero's form to the mortal giver who has the true thought.
- Rig Veda 4.11.1,2,3
