A biography that also examines important historical events and scientific discoveries in the context of the vision and work of Sri Aurobindo and the Mother, this work begins by highlighting significant facts and events in their lives. Part Two describes their collaboration to fulfill the Integral Yoga and realise their vision of a complete spiritual transformation of the world through a transmutation of consciousness. Part Three traces the Mother’s work after Sri Aurobindo’s physical withdrawal in 1950. The Ashram and its Centre of Education, and Auroville, founded by the Mother in 1968, act as laboratories for the change of consciousness they envisioned for humanity. The final chapters are dedicated to the supramental manifestation that occurred in 1956 and the Mother’s arduous work to transform the cells of her body. First published in 1997, the book is now reprinted after a gap of some years.
