Yeah I get you, there's enough death cults trying to end the world already. I mean one can take it in different ways. In the most grounded sense it's physically true. Like there's not actually a gap between physics, chemistry, biology, sociology and so on, it's one singular continuous reality. There's no actual barrier between your body and everything else, that's just a perception mainly due to a limited awareness.

Of course one can take it in a pansychism manner and I often do. It's not too difficult to get there for a more rigid materially minded individual. As you already have one just has to make a trip through epistemology first. Like classic arguments such as Descartes demon, Plato's cave, Chung Tzu's butterfly, Boltzmann brains, and last Thursdayism. That is the most grounded science based version of reality isn't as concrete as most minds would prefer it to be. If you don't know those epistemological arguments I highly suggest looking them up.

I agree, a human mind's version is likely limited. Like we're aware of the limited perception of ants and chimps yet often assume we are not similarly limited. Another one I play with is causality. Like if it's always true then everything in this moment was caused by something in a previous and those by something previous and so on until infinity or something happened that was not caused or causality and human thought isn't capable of capturing reality as it is.

All the fun stories aside I always come back to base faith. That is it doesn't matter if I'm a Boltzmann brain and reality just came into being a moment ago, the goal is to reduce needless and avoidable suffering for all minds whenever and wherever I can. Of course I suck at doing that sometimes (a lot of the time) but try not to dwell on the failures beyond the learning experience they can provide.

Like Ram Dass likes to say, be love now. If nothing matters I can still enjoy internally and externally manifesting the waking sensation of love all the same.
