"She is Reverend Mother to their Reverend Mothers. To pilgrims who seek her out with demands that she restore virility or make the barren fruitful, she is a form of anti-mentat. She feeds on that strong human desire for the mysterious. She is living proof that the 'analytic' has limits. She represents ultimate tension. She is the virgin-harlot - witty, vulgur, cruel, as destructive in her whims as a coriolis storm."
