It's not about dissolving the belief in a separate self or in free-will but about the absence of anyone to hold or ever have held such a belief. Which means that there may be such a belief but it isn't held, there isn't a place where it could be arrested, it just passes right through. What you find is an anchoring of a worlding, but an anchoring is not an anchor, is the exact opposite of an anchor. Nothing actually dissolves, but dissolution is the nature of crystallisation.
