Mirra Alfassa, French-Indian spiritual leader (d. 1973)
Mirra Alfassa (21 February 1878 – 17 November 1973), known to her followers as The Mother, was a spiritual guru, occultist and yoga teacher, and a collaborator of Sri Aurobindo, who considered her to be of equal yogic stature to him and called her by the name "The Mother". She founded the Sri Aurobindo Ashram and established Auroville as a universal town; she was an influence and inspiration to many writers and spiritual personalities on the subject of Integral Yoga.

Mirra Alfassa (Mother) was born in Paris in 1878 to a Sephardic Jewish bourgeois family. In her youth, she traveled to Algeria to practice occultism along with Max Théon. After returning, while living in Paris, she guided a group of spiritual seekers. In 1914, she traveled to Pondicherry, India and met Sri Aurobindo and found in him "the dark Asiatic figure" of whom she had had visions and called him Krishna. During this first visit, she helped publish a French version of the periodical Arya, which serialized most of Sri Aurobindo's post-political prose writings. During the First World war she was obliged to leave Pondicherry. After a 4-year stay in Japan, in 1920 she returned to Pondicherry for good. Gradually, as more and more people joined her and Sri Aurobindo, she organised and developed Sri Aurobindo Ashram. In 1943, she started a school in the ashram and in 1968 established Auroville, an experimental township dedicated to human unity and evolution. She died on 17 November 1973 in Pondicherry.

The experiences of the last thirty years of Mother life were captured in the 13-volume work Mother's Agenda by Satprem who was one of her followers.
