Mirra Alfassa, known to her followers as The Mother or La Mère, was a French-Indian 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 the town of Auroville; she was influential on the subject of Integral Yoga.

The Sri Aurobindo Ashram is a spiritual community (ashram) located in Pondicherry, in the Indian territory of Puducherry. The ashram grew out of a small community of disciples who had gathered around Sri Aurobindo after he retired from politics and settled in Pondicherry in 1910. On 24 November 1926, after a major spiritual realization, Sri Aurobindo withdrew from public view in order to continue his spiritual work. At this time he handed over the full responsibility for the inner and outer lives of the sadhaks and the ashram to his spiritual collaborator, "The Mother or La Mère", earlier known as Mirra Alfassa. This date is therefore generally known as the founding-day of the ashram, though, as Sri Aurobindo himself wrote, it had "less been created than grown around him as its centre."
