Sister Nivedita (1867–1911), born Margaret Elizabeth Noble in Northern Ireland, was an Irish social worker, author, teacher, and a devoted disciple of Swami Vivekananda. After meeting Swami Vivekananda in London in 1895, she traveled to Calcutta (Kolkata) in 1898, where he initiated her into Brahmacharya and gave her the name Nivedita, meaning "Dedicated to God." She established a girls' school in Bagbazar in November 1898 to educate underprivileged girls and actively nursed plague patients in Calcutta in 1899. Nivedita was a fervent supporter of Indian nationalism, inspiring revolutionary youth and leaders like Rabindranath Tagore and Aurobindo Ghosh through her writings and speeches. She wrote extensively on Indian cultural heritage and is the author of works such as "पथ और पाथेय: Religion and Dharma by Sister Nivedita," "Hints on National Education," and "More Letters of Sister Nivedita."
