There is a story of Alexander the Great coming across a Yogi on the banks of the River Indus, sitting quietly. Alexander asked what the Yogi was doing, and he replied, "Experiencing doing nothing". The Yogi asked Alexander what he was doing, and he replied, "Conquering the world". Both men smiled at what the other was doing, and thought "Pointless, what a wasted life". 'Wu Wei' is a concept in Taoism that could be seen to combine the two. It means 'action through inaction'. When action comes through an effortless engagement, without any attempt to force or control.
