This Foreword highlights Swami Vivekananda’s conviction that India’s regeneration was impossible without improving the status of women, famously stating that a bird cannot fly on only one wing.

To lead this mission, he chose Sister Nivedita (Margaret E. Noble), believing that the country specifically needed a "real lioness" to work for the benefit of Indian women. The text notes that Nivedita fulfilled this call faithfully through her life’s work.

The author, Swami Sambuddhananda, concludes by expressing hope that this biography will inspire educated young Indian women to dedicate themselves to the upliftment of others, thereby realizing Vivekananda’s dream of a resurgent India.
