Lyzelle Reymond wrote a book about Miss Margaret Noble or, as Vivekananda named her, Nivedita.
Here is an extract about the collaboration between Nivedita and Sri Aurobindo during the revolutionary days around 1909.
«This commanding man had become tranquil and he moved with a quiet dignity. Wherever he went people would raise their heads and bless him, for they felt he possessed an irresistible force. Thos who had once derided him as a visionary were silenced, for Aurobindo was the only leader who could utter the stirring words that Bengal needed to survive its distress.
When after his release from jail, he heard of Nivedita’s return to India, he knew she was the one he was waiting for, the living link.
Their collaboration was intimate and total, but short-lived — barely seven months to accomplish a huge task. Nivedita followed in his footsteps, contributing to his work. With them were a dozen close disciples, mostly prisoners released from Alipore jail. They looked after Aurobindo and accompanied him, for his safety was in constant jeopardy.
Aurobindo was the only nationalist leader left in a despondent and silenced party. He gave the call, rekindled the patriotic spark, proclaimed a new revolution — the inner revolution of man casting upon a declining society the spiritual element in his fully realised being: in his soul, in his vital body, in his mind and his subconscioss force.»
