For Sri Aurobindo, the important thing was always the Mother. As he explained it, the Mother has several aspects, and certain aspects are still unmanifest. So if he has represented the Mother by Kali in particular, I believe it's in relation to all those gods. [73] Because, as he wrote in The Mother, the aspects to be manifested depend upon the time, the need, the thing to be done. And he always said that unless one understands and profoundly feels the aspect of Kali, one can never really participate in the Work in the world - he felt that a sort of timid weakness makes people recoil before this terrible aspect. page 74 - Mother's Agenda , volume 2 , 11th Feb. 1961

Of course, very philosophical or learned people will pity you, but personally I don't care! I don't care. I am not a philosopher, I am not a scholar, I am not a savant, and I declare it very loudly: neither a philosopher nor a scholar nor a savant. And no pretension. Nor a littérateur, nor an artist - I am nothing at all. I am truly convinced of this. And it's absolutely unimportant - that's perfection for human beings. There is no greater joy than to know that you can do nothing and are absolutely helpless, that you're not the one who does, and that what little is done - little or big, it doesn't matter - is done by the Lord; and the responsibility is fully His. That makes you happy. With that, you are happy. page 159 , Mother's Agenda , volume 5 - 11th Aug 1964
