Sornambal also trained in Harikatha (musical discourses relating stories from Hindu culture) under Sivasubramaniam, as well as under Shri N S Ramaswamy of Nagercoil. Thus, she also became a Harikatha artiste and presented many stories from the sacred scriptures dear to the people of Tamil Nadu. Most of these were beautifully set to song and dialogue by her gifted husband Sivasubramaniam, and people thronged to witness these performances. The Harikathas she had performed include Valli Tirumanam, Sita Kalyanam, Tirunavukkarasar Charitram, and
. Her Harikatha performances were often accompanied by Sivasubramaniam and their children on violin and mrdangam. Awards and titles such as ‘Katha Gana Ratna’ and ‘Iyal Isai Kalai Chudar’ came her way, but she was most popularly known as ‘Senkottai Thangam’ (‘Gold of Senkottai’).
By 1993, Sornambal had retired from her school and resided in Chennai with her son Akkarai Shri S Swamynathan and his family. Sornambal attained the lotus feet of the Lord on 3rd March 2019.
