Balance: Of equality, or equilibrium between two contrary entities or forces.
Balance is a special case of equilibrium, which is a word used to describe more objects. Most people seek balance or equilibrium amongst the competing interests of their lives; it is regarded as the search for a state of inner peace and complete belonging.
Usually, people seem to feel they are under constant pressure away from balance, that their work/lives are regularly summited to events, accidents, duties that require them to stray from the center of certain personal balancing acts, this particular issue draws a physical analogy:
All, dynamic system, juggles and quickly strays from equilibrium. Although thermodynamics, states equilibrium is eventually inevitable, this juggling between inclinations is what permits actual work within the system.
So, actually, what moves individuals, societies, and life in general is the assurance or ability to do work between a useless chaos and a useless equilibrium.
With all this said; I would add it as an argument as to why the world has not flocked to be Tibetan Monks of harmony and equilibrium. Progress does not lie in pure chaos, nor in full equilibrium. It is found in optimizing our efficiency; because of this, we must never stop trying to obtain balance; and yet, obtaining it would be to our disadvantage.
