Eternal Calmness with activity

Inactivity, as we understand it in the sense of passivity, certainly cannot be the goal. Were it so, then the walls around us would be the most intelligent; they are inactive. Clods of earth, stumps of trees, would be the greatest sages in the world; they are inactive. Nor does inactivity become activity when it is combined with passion. Real activity, which is the goal of Vedanta, is combined with eternal calmness, the calmness which cannot be ruffled, the balance of mind which is never disturbed, whatever happens. And we all know from our experience in life that that is the best attitude for work.
