I think this is ground of any deep thinking. When both communicating parties are in a state of extending the sharing of information beyond the original data supplied by the initial communication. I think that's what it is being talked about here.
@dholu I think this conversaion what we are having itself is the best example.
Me & you both are trying to figure out things related to this or say related to life.
I am sharing a piece of information that I came across(in this case this video of J.K.) which I felt might help you in some way as at the time of sharing this I might have felt something in me as well.
So now, we both are interested in this & having seen this we have digested the information thats shared in the video. This is the first part that he tells.
Now we are thinking about it, the discussions that we are having now is the second part.
@minaminosuechi Marvellous. Thank you for sharing.
