Salon has an interview with Meredith Maran, who has recently written a memoir of her involvement in one of the 90's witch-hunts: the mass of children and women who were led to claim a "recovered memory" of abuse that never happened.
There are of course, guided meditations in many traditional Buddhist practices, but these are rather benign, extending to such things as calming one's self and so forth; you know, making new body-mind connections generally. And of course koan practice is clearly not in this league at all: it's not for nothing, as they've said in Brooklyn, that the "source language" of koans is meaningless. Koans aren't at all about replacing one narrative one has with another. It's about not having a narrative at all, really, and seeing what is and what happens.
"Recovered memory" is like "disowned voices," as far as I can see. It'd be nice for practitioners of such Voice Dialogue stuff to try to explain the differences.
