What ever is "spiritual" though? Not in a gotcha way, in legit wondering about it, because everyone i ask just says what boils do "some stuff I do sometimes", which doesn't sound like the right answer.
Every answer I've gotten boils down to being afraid of there being nothing else. People find whatever poppycock to justify the "I'm sure there's something more".
If you just have curiosity to know what "spritual" is, I'd recommend seeing a man on YouTube, his name is J Krishnamurti. He has answers to your questions. But you indeed has to have courage and willingness to listen what the man says.
It's a very condescending way to answer. Not to mention the second someone says that kind of thing there's a high chance what they are suggesting is a scam/cult/conspiracy theory or something similar.
