One can reduce his negative side, but cannot eliminate it. Sri Aurobindo's theme is there is nothing negative or undivine. Only to the view of Ego, everything other than itself is Negative. It is a new philosophy not easy to comprehend but enjoyable when you accept it, crossing comprehension. Finding no evil in life is to find heaven on earth. Sri Aurobindo never postulated a hell. Mother says if there is a hell, God is there even in hell. She could not pardon those who had invented the idea of hell.
