In 1914 the Mother voyaged to Pondicherry to meet Sri Aurobindo, whom she at once recognised as the one who for many years had inwardly guided her spiritual development. After a stay of eleven months she was obliged to return to France due to the outbreak of the First World War. A year later she went to Japan for a period of four years.
In April 1920 the Mother rejoined Sri Aurobindo in Pondicherry. When the Sri Aurobindo Ashram was formed in November 1926, Sri Aurobindo entrusted its full material and spiritual charge to the Mother. Under her guidance, which continued for nearly fifty years, the Ashram grew into a large, many-faceted spiritual community. In 1952 she established Sri Aurobindo International Centre of Education, and in 1968 an international township, Auroville.The Mother left her body on 17 November 1973.
