I... just can't see any value in forcing people to figure it out for themselves, particularly with how cryptic the lore forum can get at times. I don't even understand why it should matter how somebody came to their understanding of the concept. As long as someone is making intelligent contributions, I don't care how they got their knowledge.
Because technically there is no definitive answer; there IS, and there isn't. By "IS" I mean there is a rough, basic yet relatively consistent meaning with everyone's (correct) interpretation, but there "isn't" because it's actually much deeper than the basic explanation. If someone else explains it for you, then that does no one any good. It's almost stupid, really; someone who outright tells you it COULD be very wrong. You'd also probably feel that way when you'd do some reading of you own and come to a different conclusion than what you were told. That's happened to me with several different subjects; that's why I try to get my own interpretation instead of listening to someone's full blown answer.
In reality, there already is an answer that tells you what CHIM is in the TIL. It's called "Vehk's Teachings" and it practically tells you outright; all you have to have is a basic understanding of the relevant info.
The whole fun of anolyzing the lore is to take the cryptic info and trying to find the definitive, concrete answers out of the obscure. Trust me; most of the time, they DO exist. They either haven't been revealed yet (e.g., what Lorkhan is going to do when and if he gets his body back) or they're historical events with conflicting accounts filled with BS (e.g. what happened to Tiber Septim, Zurin Arctus, and the Underking, and creation myths).
