Interesting. Thanks for the research. I tend to make assumptions about this stuff, but it's worth remembering that communications are fraught event between two people speaking the same language in the same culture, let alone trying to glean insights from philosophic texts across centuries and continents.

To the validity of your original question, though, you bring up a good point: in myths, we find the gods bleeding "ichor," which certainly suggests a material body, even if it's of different material than yours or mine. So it would seem there's a diversity of views even within a given cultural tradition.
