They honestly vary. I'll use one, recent example.
Just this past week, I did a more formal ritual to honor MidVernal (that's what I generically call the halfway point between Vernal Equinox and Summer Solstice, calculated astronomically). As part of that, I experienced a Mystery. It was an "ah hah!" moment. Where suddenly, things made sense. I had found my truth and reached a deeper understanding of something. That something was myself. There are some issues of personal identity I've been struggling with lately, and I essentially realized (or remembered, really) that I transcend my culture's conventional boxes. I always have, and likely always will. But this knowing of the self is something that is often forgotten in the day-to-day of life. We forget who we really are, and instead go about comparing ourselves to others, and identifying ourselves based on other people or what our culture tells us. We don't let who we really are simply... be. And in that moment, I was who I am, and simply... well... was. I was able to let myself be. There was truth, deep understanding, and a sort of elation. Plus, perhaps, a quiet sense of pride.
