Mridu-di received about two hundred letters from Sri Aurobindo in Bengali. She was very, very lucky. Four days after she passed away, Nolini-da gave me a special job in connection with Mridu-di. He gave me a file and said, “Here are hundreds of Sri Aurobindo's letters to Mridu. Separate the letters you feel are important from the unimportant ones and then give both files to me.”
With a grateful heart I completed this task.
