Mother Mangalam received her education at Raffles Girls’ School and the Saradhamani Girls’ School in Singapore. In 1948, she left her family in Singapore for Malaya to complete her teacher training in a Tamil school for underprivileged students in Bangsar.
Besides teaching, Mother Mangalam assisted Swami Satyananda in relief work among the poor. The latter would go on to establish the Pure Life Society in 1949, with the aim of promoting multiracial and multireligious understanding through lectures, forums and programmes.
Mother Mangalam was initiated into Pure Life Society in 1949 as 'Sister,' and later earned the title 'Mother' in 1985. Despite early challenges at the Home, including modest meals due to financial constraints, Mother Mangalam's perseverance brought about positive changes over time. Many of the children under the care of the Home have grown up to have successful careers in medicine and the civil service, among others. In the ensuing years the Home expanded into an institution to include schools, clinics, recreational halls and vocational training facilities.
Her work among the poor and disadvantaged earned her notable recognition, including the Kesatria Mangku Negara (KMN) by Seri Paduka Baginda Yang di-Pertuan Agong in 2003, a Pingat Jasa Kebangsaan (PJK) from the Sultan of Selangor in 1955, and the Tun Fatimah Gold Medal from the National Council of Women's Organisations in 1977.
