>>11614153Its less of a thing specifically with psychedelics and more about the limitations of language, just like how trying to explain what brown looks like or how happiness feels, the experience of oneness isn't really describable. That and the addition that most people, atheists included, are susceptible to belief structures. Most people aren't atheists because they believe there is no god, rather that they do it as an opposition to organised religion. Both are ideologies to explain parts of the world that haven't or cannot be described so that we don't have to burden ourselves with the knowledge that, in fact, we will never be able to understand things.
To put things into perspective, being on psychedelics can feel like a near-death experience. Most people when subjected to that will try to explain what they felt, and when science can't explain it, then they will turn to spiritual structures which do. The problem is that this is more of a problem of philosophy - where do I begin and where do I end? Am I just a brain in a jar or am I this whole thing experiencing itself from a limited perspective. Either way if you feel like you're 100% unable to be convinced of this, taking a psychedelic will explain a lot and even if you don't agree with shit like 'I am the universe experiencing itself' then at least you can *feel* what someone means when they say this and at the end of the day that's some pretty interesting shit to learn.
