This book presents most of Mother's Matrimandir talks, including how she conceived the idea for this special concentration and meditation building in Auroville. Her talks about this subject were with the architect Roger Anger, various disciples from the Sri Aurobindo Ashram, and various Aurovilians. Her reflections on such a project started as early as 1954, and the talks ended with her passing on 17th November 1973.

All other construction decisions after she had left had to be made by Aurovilians and the group of architects and disciples who worked with her on this project for about 8 years, from 1965 to 1978.

The Matrimandir was finally officially opened in 2008. The book also contains an introduction by Debashish Banerji.
