People are

growing fast, looking out of their head, through eyes. It is a very indirect way of seeing.
Growing and seeing some of this world. Understanding is done by comparing...?
Or how would one of you explain how that works?
Understand. Seeing and comparing.
How do these things fit together. Or do they not fit together at all?
In that sense understanding would be again filtered, again only a tiny part of the thing we are looking at.
Can everybody follow?
Nothing really new, isn't it. Millions of smart people already were more or less successfuly trying to think these thoughts...

Maybe it is better I lose this one like the yesterdays one.

Whoever wants to say something, be aware, your eyes are looking, your brain is seeing and your mind is the one with a chance to understand.
So mind the mind!
