Hmm... could the Mental Resistance be a result of devout faith in Yawah? The idea of Yawah in the post-Jabbar hallucination was described as a grand structure that would protect, in an almost paternal way. Perhaps there's something to that.
That would imply, since the same resistance is granted to Qudssi (a believer) and the acolytes, that Yawah is not a conspiracy or a lie, that Cygnus and his acolytes actually believe in Yawah, and that their belief has a measurable effect. Interesting.
