Faith is actually a mechanism to ensure change keeps happening. It suspends the “sealing off” of the mind that replaces sensory input with projected theory.
Motherfucker. What do you think religious doctrine is and faith in it does.
Buddhism uses presence for the same function abrahamic religions use faith.
Buddhism, if you drill down into the monastic core, is introspective psychology. It has much more in common at that level with what's considered philosophy in the western tradition, in particular Stoicism. It arrived at that knowledge during an initially productive scientific phase, meaning theorising and experimenting, later on alas it fell away from that and various groups fell back into that exact sealing off you mentioned, not investigating any more but accepting the map of the territory they read in monastery school as the territory. Religious innovation generally follows that kind of repeating pattern over quite long time-spans.
It’s a source of noise to keep the conceptual structure from gaslighting the adherent into being unable to see what’s in front of them.
You could also, you know, just be sceptical. Heck, even be a capital-S Sceptic them and the Stoics disagreed on like exactly one point which from a certain POV is semantics.
...not to mention that that's not how the mind works. It's not how life works. If you want entropy then it's going to come from the outside, everything about life itself is geared towards minimising entropy on the inside, at the expense of accelerating its progression on the outside. (Yes the purpose of life is to hasten the heat-death of the universe, different topic). What may seem like internal randomness to you is merely your degrees of freedom doing their thing, the capacity to react to the same external stimulus in different ways depending on your internal state. It's a chaotic system (and overall you are) but it's definitely not noise, not from the POV of the organism itself: It is not subject to it, but is employing it.
If, OTOH, all you wanted to say is "hey I found a way to stop walking into lamp posts and I describe it like..." then first off congratulations, keep up the good work, but also I don't care about your half-arsed theory. Maybe if you didn't connect it up with the concept of noise it would've at least ended up being internally consistent. Keep not having theories if you want to see actual freedom from that conceptual stuff. Maybe investigate why you felt the need to to explain the experience instead of taking it at face value.
