The human action guided by his ignorance obstructs the natural flow.
I would say the opposite of that premise.
The human action guided by his intelligence obstructs the natural flow...
(I'm not saying for better o worse - but when we not sentient beings, we were more 'in the natural flow' than when we started thinking...?)
As for the aliens and furniture...lol
lol...
What I was referring to is not that we are completely ignorant, but that our actions are guided by ignorance because they ignore the natural order, despite being able to know many other things.
