I've only heard glimpses of the oddities since I listen to a youtube channel run by a therapist who studied yoga to become a monk. He talked about a practice (to not do) where you drive your heel into your taint which if done long enough it makes you infertile. He also talked about having to do a meditation alone with a man to unlock his erotic chakra. He said he didn't do anything with the man but people definitely abuse that practice and not all monks are so clean.

But there are a lot of weird practices around the proper way to have food. Judaism has had a lot of different variations of how to eat food kosher. I've read some people have different plates depending on if the food is a plant, diary, or meat. Some people think you have to wait a few hours before eating dairy and meat so they don't mix. But of course, you can have seafood, cheese, and bread at the same time (so long as it isn't a crab or shrimp) but you can't have a cheeseburger. You also can't have imitation bacon. Makes no sense
