Pravrajika Bhaktiaprana was the fourth President of Sri Sarada Math and Ramakrishna Sarada Mission. Under her guidance, the Math and the Mission progressed in various ways.

Born in October 1920, Mataji had seen many of the direct disciples of Sri Ramakrishna. Her previous name was Kalyani Banerjee. Her schooling was in Sri Sri Saradeswari Ashram and the Hindu Girls’ School under Gouri Ma, a disciple of Sri Ramakrishna. She had her nursing training in the Ramakrishna Mission Sishu Mangal (now known as Seva Pratishthan). After that, she lived in an Ashrama started on Swamiji’s ideal of renunciation and service till, in 1950, along with other members of the Ashrama, she joined the Ramakrishna Mission as dedicated worker. At that time i.e. 1950 the Mission started Matribhavan, a maternity hospital where she was sent with others to serve.

She was an initiated disciple of Swami Vijnanananda Maharaj and received sannyasa from Swami Shankarananda in January 1959 along with seven senior members forming the first batch of Sannyasinis of the Ramakrishna Order. She became a Trustee and a Member of the Governing Body of Sri Sarada Math and the Ramakrishna Sarada Mission in 1959 and 1960 respectively. Soon after, the Ramakrishna Mission transferred the Matribhavan hospital to the Ramakrishna Sarada Mission in November 1961. Thereafter, she took charge as its Secretary and gave herself heart and soul for the development of the hospital. Her life was a wonderful combination of work, spiritual austerity and self-effacement.
In December 1998, she was elected Vice-President of Sri Sarada Math and the Ramakrishna Sarada Mission and in April 2009 became the 4th President of the Order. Her outwardly strict personality gave way to her innate affectionate motherly nature when she became the President of the Order.
