Aruna Sairam, the Sangita Kalanidhi designate, opens the door and ushers me in with a warm welcome on a languid Sunday morning to her house, named Mantralayam, a neat compact structure nestled inside a street in Abhiramapuram, Chennai. The large picture of Aruna’s favourite Krishna stands tall overlooking the entrance and welcoming the guests. Her love for Krishna began even as a child because of her mother Rajalakshmi Sethuraman who used to organise congregations in their simple flat in Mumbai.
