UPDATE based on edit RE: Maya being a person's name
"There's Maya to think of in all of this, too."
This means that whatever the circumstance being discussed, it's important to bear in mind the impact or opinions that Maya has.
So the person saying that is trying to stress you shouldn't be making a decision without considering Maya's interests. In this case it seems like perhaps someone is being asked to make a sacrifice on principle, and perhaps Maya is their wife/daughter/etc. So they are saying there's more to consider than just the principle...because she is important as well. If one were to sacrifice their life for this principle, she might be left alone as a result.
Prior to that being clarified:
Maya could be a person's name. And it's computer software for 3-D rendering. If you look at the disambiguation page on Wikipedia, there's a bunch of references:
In terms of go-to for me, if you saw that sentence and it wasn't obvious from context (civilization, person, software), I'd assume it refers to the "illusion" concept:
Because that's the most "context-free" form of the word I'd imagine anyone using.
In other words, I'd default it as "you should be aware that what you're seeing might be an illusion, and the truth is deeper". But that involves a lot of presumption. Context is going to drive the interpretation of a word used to mean so many different things.
(Again, the "in all of this" being very contextual as well. Whatever the concern is in the surrounding text--the focus of the conversation.)
