I still disagree with Ishtar on the use of the books for knowing the difference between the two. It is not always evident.
For the record, I'm not recommending against reading the books. I agree that they're a good tool for a would be kajira to tell the difference between a Gorean and a wannabe.
I just don't think it's a prerequisite for a girl to have read the books in order for her to come to be owned by a Gorean. Nor do all Goreans expect their kajirae to have read, or read the books at all. Like I said, my friend's Master is Gorean, and he has no desire whatsoever for her to ever read the books (though he wouldn't prohibit it either, as far as I know, should she become interested).
Personally I don't believe a would be slave should be looking to be owned by a Gorean, or any other flavor of Master. She should be looking to be owned by a man who can master her, regardless of the personal philosophy he holds to. If that means she ends up with a Gorean, so be it, if it means she ends up with a non-Gorean Master, just as well.
However, if for some absurd reason she's got her heart set on necessarily being owned by a Gorean and nobody else, reading the books is indeed the best tool out there to tell a Gorean from a person who just picks up little bits from the books to juice up their personal flavor of slavery. I just don't see anything wrong with a slave ending up with a person who just picks up a little flavor from the books to augment their personal style, providing he can master her. As such, I don't think it's really necessary for a slave to be able to tell a Gorean from a non-Gorean.
I can be your whore
I am the dirt you created
I am your sinner
And your whore
But let me tell you something baby
You love me for everything you hate me for
