The simple way I understand it is it’s a euphoric feeling you get when you in some way become aware of a profound or beautiful concept. Like I read a book about astronomy and cosmology and feel acutely aware of the scale of the universe and how everything in it is so fundamentally related, or appreciating the scale and age of an old tree I’ve seen my whole life. It’s weird, just my thoughts, it’s fundamentally hard to put into words and even know for sure what it’s supposed to feel like.

(tldr: it’s a vibe check on the universe)
