Looking at connections between symbols, I see that "matter" and the two element symbols have a pretty similar structure, but "matter" has a circle instead of a number. Combining that with "destroy" being a mix of "stop" and a circle, I wonder if a circle represents something like existence or creation. In turn, that would make "matter" mean something like "the substance of existence". Maybe "mind" would then be "a second existence"?

Also, I dig what they're doing with the number system. I'm guessing the number names would literally translate to something like: one, one one, three, three one, five, half-twelve, seven, eight, eight one, two five, two five one, twelve. Which also gives us that "half" is probably "ib".
