I could appreciate the article only when I read the context - "What is the difference between introspection and awareness?"
I saw few comments and am not sure if responding to them is acceptable or not. So just want to give an example. If you see a child crying, you could have 3 different feelings (i) if it is your child (or generally if you know the child) then sadness or worry (ii) if you don't know or are occupied otherwise, then indifference (iii) if there is a history behind or for some other reason there might be irritation.
Your feelings influence the way you see that child crying. However, there is a 4th way to look at the same incident - you experiencing the pain which forces tears to flow even though you are not crying at that moment. You are still experiencing feelings but this time there is communion between observer (you) and observed (child), which was missing in all the 3 cases above.
