Subhas Chandra Bose's own mother Prabhavati Devi, who gave birth to Subhas, was a great spiritual lady. She was instrumental in inculcating greatness and spirituality in young Subhas. Young Subhas used to read Gospel of Sri Ramakrishna or Sri Ramakrishna Kathamrita in Bengali to her and thus got attracted to the teachings of Sri Ramakrishna, before he was introduced to Swami Vivekananda. To her, Subhas wrote an extremely touching letter when he was only sixteen years old, that showed his maturity where he told her that "India is God's favourite Nation and that is why God is reborn here again and again." Subhas's second mother was Sarada, his dhatri mother, or governess, who took care of him in childhood. She was alive when Subhas became President of Congress. Subhas's third mother was Bibhavati Devi, his mejobouthan, or wife of mejda (second elder brother) Sarat Chandra Bose. Bibhavati Devi took utmost care of the household and took up lion's share of responsibilities when Subhas and Sarat were both arrested. Subhas's fourth mother was Basanti Devi, the worthy wife of Dshbandhu Chittaranjan Das, who according to Prabhavat Devi, was the real mother of Subhas. Subhas visited her house late at night to eat "bhate bhat" cooked by her and all his demands were placed before this mother. To Basanti Devi also Subhas wrote a very touching letter from jail in Mandalay, after Deshbandhu's death. Subhas's fifth mother was Ila Bose, his niece, who nursed him back to life, like a true mother, and played a stellar role in his escape. After this role was over, Ila's life was short. As if she was born to play a critical role in Subhas's life.
The sixth mother of Subhas was Jagadamba Saraswati Devi, if we consider that Subhas was metamorphosed to Mahakal. She took utmost care of Bhagwanji throughout.
In our Puranas, God Skanda or Karthikeya had six mothers. He was the lieutenant of the Devas against the Asuras and was the son of Durga. He was a heroic and a valiant warrior, extremely good looking and was favourite of all. There is a controversy in Purana whether he was married or not. According to one version he was not. That was ahy he was Kumara.
An interesting analogy perhaps!
