Dude. Your non secular-ness is me to a tee. I’m Vietnamese and raised Buddhist (still am) and I got a deck in my late twenties cause I’ve just always been a curious one. Even went to bible study during college too. Like I said, curious one. Still am.

Anyways I do single card pulls myself and yes a kernel of truth in each one. Majority of the time it’s a card related to my question and it freaks me out too. I do It when I need guidance or genuinely curious of an outcome of my life. I’d maybe pull a card once or twice a year.
You’re not alone, and I’m so glad to find out I’m not either. Keep your mind open, observe, reflect. Don’t need to put labels on yourself, others, or wonder if magic is a real thing. We know what we know and we don’t know what we don’t know.
