The Lindgren spirit was discovered by T. Lindgren of JAME, technical operations division. The Spirit is captured in vacuum inside a rotating spirittech drum and communicates through superconductive, loquacious pseudo-ectoplastic tubes connected through safeguarded enzyme portholes mounted only on the underside of the protective outer bio shell. This is good for saving energy, but caps the effectivity of the instinct suppressing brain stem lock and can theoretically empty the spirit of its program if a strong enough native soul-pulse reaches back inside the crystal through a burnt out porthole. Chances for this to happen are small, but it's good to be aware of it if you ever try to unscrew the drum.
