As a child Sarada was devoted to God, and spent most of her time helping her mother in various household chores like caring for younger children, looking after cattle and carrying food to her father and others engaged in work in the field. She had no formal schooling, but managed to learn the Bengali alphabet. When she was about six years old, she was married to Sri Ramakrishna, according to the custom prevalent in India in those days. However, after the event, she continued to live with her parents, while Sri Ramakrishna lived a God-intoxicated life at Dakshineshwar.

In 1872, his wife Sarada, now nineteen years old, came from the village to meet him. He received her cordially, and taught her how to attend to household duties and at the same time lead an intensely spiritual life.

Although Sarada continued to stay with him, they lived immaculately pure lives, and their marital relationship was purely spiritual. It should be mentioned here that Sri Ramakrishna had been ordained a Sannyasin (Hindu monk), and he observed the basic vows of a monk to perfection. But outwardly he lived like a layman, humble, loving and with childlike simplicity. During Sri Ramakrishna’s stay at Dakshineswar, Rani Rasmani first acted as his patron. After her death, her son-in-law Mathur Nath Biswas took care of his needs. Sri Ramakrishna looked upon Sarada Devi as a special manifestation of Divine Mother of the universe. In 1872, on the night of the Phala-harini-Kali-puja, he ritualistically worshipped Sarada Devi as the Divine Mother, thereby awakening universal Motherhood latent in her. When disciples began to gather around Sri Ramakrishna, Sarada Devi learned to look upon them as her own children. The room in which she stayed at Dakshineshwar was too small to live in and had hardly any amenities; and on many days she did not get the opportunity of meeting Sri Ramakrishna. But she bore all difficulties silently and lived in contentment and peace, serving the increasing number of devotees who came to see Sri Ramakrishna.

Although she was highly venerated for her spiritual status, and literally worshipped as the Divine Mother, she continued to live like a simple village mother, washing clothes, sweeping the floor, bringing water from the pond, dressing vegetables, cooking and serving food. At Jayrambati she lived with her brothers and their families. They gave her endless troubles but, established as she was in the awareness of God and in Divine Motherhood, she always remained calm and self-possessed, showering love and blessings on all who came into contact with her. As Sister Nivedita stated, “Her life was one long stillness of prayer.”

In the history of humanity, there has never been another woman who looked upon herself as the Mother of all beings, including animals and birds, and spent her whole life in serving them as her children, undergoing unending sacrifice and self-denial. About her role in the mission of Sri Ramakrishna on earth, she stated: “My son, you know the Master had a maternal attitude (matri-bhava) towards everyone. He has left me behind to manifest that Divine Motherhood in the world.”

On account of her immaculate purity, extraordinary forbearance, selfless service, unconditional love, wisdom and spiritual illumination, Swami Vivekananda regarded Sri Sarada Devi as the ideal for women in the modern age. He believed that with the advent of Holy Mother, the spiritual awakening of women in modern times had begun.

Under the strain of constant physical work and repeated attacks of malaria, her health deteriorated in the closing years of her life, and she left the mortal world on 21 July 1920.
