In the framing of left/right brain, we have many rich experiences that are not a part of what we verbalize or what we can write down. Eye contact with another human is the example I'd give. Shared holding of a gaze. It can communicate so much...even a fleeting glance is full of rich content. I'd say that kind of knowledge exists only in-between. There is wisdom there too, a compassionate or supportive look...all understood without a word.
