The input to the divine hallucinatory aspect of the bicameral mind was auditory. It used cortical areas more closely connected to the auditory parts of the brain. And once the word of god was silent, written on dumb clay tablets or incised into speechless stone, the god's commands or the king's directives could be turned to or avoided by one's own efforts in a way that auditory hallucinations never could be. The word of a god had a controllable location rather than an ubiquitous power with immediate obedience. This is extremely important.
