This book contains The Mother by Sri Aurobindo and the Mother's spoken comments on passages from that book, made during her evening classes at the Ashram Playground. The first set of comments were given in 1951 and the second in 1954. From the publisher's note, "These comments do not form a systematic commentary on Sri Aurobindo's work, but are rather explanations of certain passages, phrases and words. The Mother usually began the class by reading out a passage from the book, then commented on it or invited questions from those gathered around her."
