I think I understand what you are saying with this article.

My understanding is that simply observing and/or listening to someone with a non-judgmental awareness facilitates a positive feedback loop. An energy exchange occurs whether this is acknowledged or not that benefits the observed and the observer. I find that having non judgmental awareness can allow you to download knowledge,insight,information about the observed and about yourself(the observer.

I like to practice this anonymously on public transport, I imagine that my non judgmental awareness of that particular person/place or thing allows a positive feedback loop in a way that they may or may not consciously be aware off.

I imagine that observing in an non judgmental way is my empowered state that I can always exercise to be a positive force in the world and to fulfill part of my purpose.
