Yes i have difficulties to describe it too.
I would even go further.
I would say that some parts of thinking "transform" into the "above thinking".
Now there come things from "below" into the normal thinking awareness, like when something from "below" is sucked into the "normal thinking" because of an arising vacuum.
This seeming vacuum is caused because "normal thinking"-things went into the "above thinking".
Is this comprehensible? If not I try to figure out an example.
