I think we foreshorten our own viewpoint if we consider any state of mind, or society, or government as final. Growth and change! We can't get away from them.
I think there are hard-liners inside of Iran that think it is the right thing to do to oppose us, to seek to destroy Israel, to cause havoc in places like Syria or Yemen or Lebanon, if they don't change at all, we're still better off having the deal.
The nearer a conception comes towards finality, the nearer does the dynamic relation, out of which this concept has arisen, draw to a close. To know is to lose.
When you get free from certain fixed concepts of the way the world is, you find it is far more subtle, and far more miraculous, than you thought it was.
It is the free alone which never changes, and the unchangeable alone which is free; for change is produced by something exterior to a thing, or within itself, which is more powerful than the surroundings.
