(...) it suggests one would need more than rationality to truly understand reality.
I’m not sure what you mean. In such a case, rationality dictates that IFF you truly want to understand reality, you should find that “more” that is needed and use it instead of rationality. This is the rational course of action. Therefore it is rational to do that thing “instead of” doing rationality. Thus being rational means doing this thing that leads to understanding reality.
This seems to imply that if you keep recursively applying rationality to your own application of rationality, you end up finding that that which leads with highest probability to the desired goal is always rationality.
