There is a mysticism aspect that falls under the umbrella of Buddhism, too. Like if one is enlightened sufficiently, they can ascend to another life form after death, otherwise it's reincarnation to try again. I think there's more to it than that, but honestly haven't delved too much into it because the philosophy is where the useful stuff is.

And ironically, an aspect of enlightenment is accepting that suffering is a part of life so that you don't suffer more being upset that you have some suffering. Getting that one was like a switch for me and life has generally been much happier. Things don't "ruin my day" anymore.
