FWIW I have a friend who is deep into spirituality, still works at a FAANG but definitely feels like he can attain higher states of awareness in his meditations. I don’t see him active on social media, he leads a reasonably ascetic life and so on.
This person doesn’t have much success in making others believe. At best, he gets ‘hey, I am happy that you’re happy’ from folks like me, most feedback is around ‘mystic woo’. I have another friend deep in this world, but she balances it with real world and doesn’t really proselytize.
I think it is very much a catch 22. You won’t believe it unless you’re doing it. So if belief is required for you to give it a shot, that’s a non-starter.
I would say try it out and make up your own mind! What do you got to lose anyway - stay away from holy men who make you uncomfortable, start with books or YouTube!
