Sister Nivedita, born as Margaret Elizabeth Noble, was a Scots-Irish social worker, author, teacher, and disciple of Swami Vivekananda. She met Vivekananda in 1895 in London and traveled to Calcutta, India (present-day Kolkata), in 1898. Swami Vivekananda gave her the name Nivedita (meaning "Dedicated to God") when he initiated her into the vow of Brahmacharya on March 25, 1898. She had close associations with the newly established Ramakrishna Mission. However, because of her active contribution in the field of Indian Nationalism, she had to publicly dissociate herself from the activities of the Ramakrishna Mission under the then president Swami Brahmananda. She was very intimate with Sarada Devi, the spiritual consort of Sri Ramakrishna and one of the major influences behind Ramakrishna Mission and also with all brother disciples of Swami Vivekananda. Her epitaph aptly reads, "Here reposes Sister Nivedita who gave her all to India."
Nivedita wrote in 1904 to a friend about her decision to follow Swami Vivekananada as a result of her meeting him in England in November 1895:
"Suppose he had not come to London that time! Life would have been like a headless dream, for I always knew that I was waiting for something. I always said that a call would come. And it did. But if I had known more of life, I doubt whether, when the time came, I should certainly have recognized it.
"Fortunately, I knew little and was spared that torture. . . . Always I had this burning voice within, but nothing to utter. How often and often I sat down, pen in hand, to speak, and there was no speech! And now there is no end to it! As surely I am fitted to my world, so surely is my world in need of me, waiting — ready. The arrow has found its place in the bow. But if he had not come! If he had meditated, on the Himalayan peaks! . . . I, for one, had never been here."
"The mother's heart, the hero's will The sweetness of the southern breeze, The sacred charm and strength that dwell On Aryan altars, flaming, free; All these be yours and many more No ancient soul could dream before- Be thou to India's future son The mistress, servant, friend in one." —A benediction to Sister Nivedita by Swami Vivekananda
