Ah'hei is the mental conditioning programmed into the Sazashi by the Verin Haimarchy back when they first created them. Ah'hei serves as a Sazashi's overriding psychological drive, sometimes superseding even sexual or survival urges in extreme cases.
Ah'hei has several mental states which it triggers. These states overlay their normal mental states, affecting them rather than replacing them.
As a Sazashi, there's a constant internal battle we all face. We were built for servitude, physically designed for certain tasks and neurologically conditioned to excell at those tasks and take pleasure in them.
Is it submission to do these things because we enjoy them? Should we deny ourselves these things, just to spite the tyrannical natures of the Verin Haimarchy? Should every Kajh be an artist because she was built for manual labor, and should every Helyk avoid the arts for the same reason?
Or do we each stake our own paths as induviduals, and decide for ourselves who we are—whether that coincides with our 'purpose' or not.
If we live blindly by it, we allow it to control us. If we do the opposite of it to spite it, then we have again allowed it to control us.
All we can do is live as ourselves, and decide day by day what that means.
