- the world I see is not the same as the world you see.
- we see the same physical world but the perception, emotion, feeling, interpretation, etc are not the same.
- no one is in the same world.
- we can confine the world as the physical world only, but it limits "me" as a whole body,
- as a result, you don't know "me". huh? we've heard of it in many movies, haven't we?
- even if we do, the sensory is not the same for everyone. what is red? how red? it is totally different with everyone. no one sees the same red.
