- The scope of Buddhahood
- The scope of jhana
- The specifics of karma
- The origin of the universe (or the cosmos, assuming many universes exist)
These are four things they are not supposed to think about because they lead to insanity and do not lead away from suffering.
But do Mahayana Buddhists have any explanations, though, as to the true nature of these four things?
Time, gravity, light, karma; these four things seem inexplicably linked in a way I don't fully understand but vaguely imagine. Maybe I just need to find a Lama, hahaha.
Don't know why I conflated Theravada with Hinayana.
I guess when I wrote the OP, I was a deluded Mahayana sectarian, lol.
