Taut is the rope that the tightrope walker treads on. It bounces some, and sways a little, but the balance bar he carries counteracts those forces and stabilizes his slow gate from one end of the rope to the other. 
In my Tension Model, think of this taut rope as a sort of bridge that connects 'realities'. 
Uneasy standoffs between people are kind of like a taut rope bridge. In contentious matters, where belief systems are highly divergent, both sides hold onto their positions with a firm grip and the continuation of any matter between them is the tightrope walker moving back and forth between fixed poles. There is little give and take occurring. Neither position is surrendering or sacrificing much, and the tightrope walker can't carry much to either side anyway, so the bridge stays more or less the same. It's limited in capacity, narrow in scope.
But what if one end was loosened? Advantage may then seem to be gained for one of the parties as the bridge would disappear and a new way of reaching the other side could be be made, perhaps an easier way (or a more arduous and time consuming way). 

Tension between positions is a 'fact' of life that most of us are born into. There is a distance between what we desire and how that desire can be fulfilled and usually acts of sacrifice are called for on the less powerful one's part, the expenditure of a great deal of time and effort, in order to reach the other end of the rope, the place where goals are realized. There is the 'where we are', and there is 'the other end of the rope', where our desire awaits us. 
But what if achieving our desires was as simple as letting go of any rope completely and trusting that what we desire will come about? We make no physical or mental effort to reach the goal other than that which is necessary at the time. Initially, the goal must be visualized as clearly as possible, and any contrarian thoughts about achieving the goal must be vanquished to the best of one's ability. After that, the goal begins to make it way towards you as you hold it persistently in mind, though you may not see any 'movement'. 
Action steps may be called for from time to time to bring that which is desired ever closer, but this involvement by you occurs only when prompted, and by 'prompted' it means you have the undeniable urge to perform the next action step. This urge to do can't be mistaken if you pay attention to the difference between feeling the need to perform an action step and restlessness. They are two very different things. 
Lastly, you stand by, ready to receive. That which you desire eventually lands on your doorstep, or you step into it, only because you wanted it and did the necessary at-the-time steps to realize it. 

In a tension free existence, there is never any real battling involved. The only battle you ever have is with yourself.
