That is a brilliantly written line!
But now I am thinking about the Principle of Duality.
Both, rock and water, are part of Nature and help co-create it.
We have things we love at one side and things we hate at the other.
And both help us move forward. Is an ideology bad? I think so. Does it have its value and place in this world? I think so, too.
Sorry, I always get hanging between the opposites and seek what is right, left, or wrong.
