Thank you for finally answering my question regarding what OT postulates are.
You haven't yet explained what converting an OT postulate into inspiration is, but I think I can fill in the rest. It means that you form an intention or wish ("postulate") for a change ("to be a cause over") in the real world ("MEST"), and instead of the change actually happening, you derive insight or ideas ("inspiration") by contemplating why it did not happen.
This is indeed an enlightened feat, one that can only be rivaled by, say, a seven year old who prays for a pony, and eventually comes away with the insight that neither God nor the universe will materialize a pony out of nothing for her, and that she should be more understanding of the sacrifices her parents make to provide her with what she does have, and that instead of praying for a pony she should be praying for richer parents. (Higher toned insights are more likely at a more mature age.)
Note that the Scientology version of this, "OT postulate into inspiration," only works if one starts with the assumption that you are specially empowered such that your wish (postulate) must and shall come true. Otherwise there is nothing to contemplate; if the answer to "what went wrong?" were "duh, wishes don't come true by thinking about them" (the actual correct answer), no further insight would be forthcoming. So the fiction that you are exercising or attempting to exercise actual OT powers over reality is necessary to achieve the mental benefits actually derived.
I think this is a good explanation for why you and other Scientologists find it necessary and appropriate to claim or imply, in the face of scientific knowledge to the contrary, common sense to the contrary, and decades of inability to actually demonstrate any such claim, that OT superpowers "like in the Matrix" are real. Do you agree, or do you have anything to correct or add?
Respectfully,
Myriad
