This book contains “treasures” collected by Champaklal during his lifetime — notes, letters and messages written by Sri Aurobindo and the Mother. About them Champaklal once said: “These writings to devotees are most valuable. I have preserved them not for myself but for others, so that they may receive what I have received from them.” Some of them are not published elsewhere. The book also includes some early conversations of Sri Aurobindo and some sketches by the Mother.
