Nah. Oat, or pea milk.

Unless you’re one of them weirdos who actively likes 2% milk then sure soy or almond.

Buddha was Indian. And 6th century BC. It did spread to Asia, but it was not theirs originally. They did tend to adopt more philosophical things, like Confucianism and Taoism around that time.

But there’s also older stuff. Myths, gods, yokai, Djinn, etc. throughout Asia. With plenty probably fitting what your definition wants, but idk. I would start looking for stuff older than Buddhism, Taoism (or legalism), or Confucianism.

Just wanna say thanks, that visual really got me.
