It was the Mother who named the organization Sri Aurobindo Society, after Sri Aurobindo. She created its symbol, taking the existing symbol of Sri Aurobindo and enclosing it in a diamond. She gave it the motto:

“To know is good, to live is better, to be, that is perfect”

It is the symbol of Sri Aurobindo, with lines joining the apexes of the two triangles to form a diamond. The significance of the diamond, according to Sri Aurobindo, is the Mother’s light at its intensest. While Sri Aurobindo was the medium of Divine consciousness and the Supermind, the Mother became the bridge between Sri Aurobindo and the world of the Sadhaks and Seekers.
