I have a serious question to people here describing themselves (as I understand it) as thinking in words and whole sentences: How can you think about concepts which cannot be put into words or for which no words exist? Do you have to come up with elaborate verbal descriptions of abstract concepts in your head before you can think about them? If so, don't you think that any verbal description is essentially incomplete…
What is a concept which cannot be put into words?
Further to that end, the clarity of a totally calm mind. Words can be used to poetically convey that state — but while they get close, I’m not sure they can adequately describe what pure thought is.
