Ive been "blessed" with many experiences i describe as spiritual.
Well, being around death was pretty cerebral for one. Felt sad obviously, but like a full awareness my life had suddenly changed. You sure appreciate things differently.
Psychedelics did (...or do?) the trick in my case, but your mileage may vary, what can i say. Buyer beware. I come away with profound insights that help me cultivate a sense of, or develop a "relationship" with, you know... the divine. It feels like a trip, man. And then afterwards life still seems to confirm its trippiness.
Magick is another thing i might say triggered a spiritual experience. My first real "spell" was a simple chaos magick sigil casting experiment, and it blew my mind. I had what felt like a full blown psychedelic experience from that, even though i wasn't on anything.
Also, at the rehab i went to (p m unrelated, but not not part of my experience), they offered "Holotropic Breathwork". The things i experienced in that state while totally sober were some of the most viscerally profound, and life-changing intensities I've gone thru. Far out.
Yoga & meditation are also good catalyst's. I got those as tools in rehab, too. Even with shoddy commitment to them, they seem to continue deepening the whole syndrome.
Shit can still suck but u learn to roll with it, cuz we're all one thing experiencing itself,... so i guess it's fine. 🤷
I use it for myself all the time. Its the best medication free approach ive tried persoanally
