Mata Kalavati Aai was born to the pious parents Smt. Sitabai and Mr.Shantaram Kalyanpurkar of Karwar,Karnataka State,India.Mr.Shantaram had a dream of Goddess Durga informing about her incarnating in his family. Soon thereafter in 1908, Holy Mother was born at the auspicious time on the day of Rushi Panchami in the month of Bhadrapad.She was named as "Rukmabai".
To a common man she taught how to spiritualise their daily lives.She formed a special prayer booklet called 'Balopasana' for children which has become very popular.Though illiterate (she had education only upto 3 rd std. in Kannada) she would throw a flood of marvelous light upon the obscurest corners of Indian scriptures (Vedas, Puranas) and bring out fundamental principles in such simplicity and clarity that even a lay man could understand it.
