stream...the incessant flowing water across many obstacles

“Freedom from activity is never achieved by abstaining from action. Nobody can become perfect by merely ceasing to act. In fact, nobody can ever rest from his activity even for a moment. All are helplessly forced to act. . . .
A man who renounces certain physical actions but still lets his mind dwell on the objects of his sensual desire, is deceiving himself. He can only be called a hypocrite. The truly admirable man controls his senses by the power of his will. All his actions will be disinterested. 
Activity is better than inertia. Act, but with self-control. If you are lazy, you cannot even sustain your own body.”  --Bhagvad Gita
