>>212155350There's a story, I don't remember where it's from in the canon, but it discusses a bunch of angels living in a heavenly realm
They're all lounging about, experiencing bliss, when suddenly one of them disappears and they're terrified since they never think about death
They go looking for her and they realise she's been reborn in a Hell realm and is now suffering a miserable existence
At that point they all try to get the Buddha to teach them how to achieve nirvana because they realise even as an angelic being who lives for a very long time, they aren't free from Samsara
