Bhattacharya prefers to call his instrument 'Shata Tantri Veena', the original Vedic name. His mission is to revive the age-old Indian name of this very traditional classical instrument, (reference of which has been found in the 'Vedas'), instead of the derived Persian name. Bhattacharya strongly believes that Indian classical music is like a therapeutic (positive) drug. The early introduction of this 'drug' in schools and colleges shall help in bringing forth and develop the sensibilities of a young adolescent mind, making him/her more humane and also help negate the bad influences. He doesn't believe in making musician out of every individual, but he strongly believes that through the power of music individuals can be made compassionate, peace-loving and of course musical. Bhattacharya is firm believer in the continuance of legacy and rich heritage of Indian classical music and in the Guru-Shishya parampara. To further this dream and belief he set up a unique institution Santoor Ashram a traditional 'Gurukul' in a village near to Calcutta. He dreams that one day, quite soon, Indian classical music will be introduced at the grass root level, in schools and colleges. Bhattacharya's humanitarian nature is manifested through his efforts of imparting music lessons to very talented yet financially underprivileged music students. The Ashram provides them free stay and hospitality instruments and of course music lessons thereby maintaining the purest form of Guru Shishya parampara. Santoor Ashram, situated amidst the peaceful tranquility and greenery of rural Bengal, has helped shape the careers of some of the recognized musicians of today.
