Unfortunately I can't recommend any lemmy communities for this. I've found a good one for general 'woo' like paranormal, UAP etc but not for spirituality (I'm not into paranormal stuff anymore as there's so often a logical explanation, but with UAP.... 99% have a logical explanation, that 1% which doesn't fascinates me).

I mostly see any given religion as an ancient, outdated 'how to live your life' manual that (imo) we should be well beyond needing. Like, I don't need a book to tell me that killing someone or stealing their bike is wrong! Also if I'm being honest I see them in modern times merely as systems of control, a way to manipulate large groups of people and steal either their money or devotion. Buddhism stands out to me in that regard as a genuine attempt to help people gain happiness and peace in their lives. Sadly as with many good things, there are people corrupting it (eg Myanmar). But after reading so many other religious texts, it's the only one that venerates the human and tries to get them to lift themselves to happiness. All the others are various threats, demands and commands to do this or that otherwise we'll burn for eternity.
