.  Everything needed is contained in the Blood; just as Mat experienced Aemon's life during his Healing, the Columns simply bring the applicable Old Blood Memories to the surface and allow the candidate to experience them; including any and all cultural baggage  Everything needed is NOT contained in the Blood for the type of future we see. We see future civilization. We see future generations. That information does not exist in the Blood. There is no proof that the blood can or would hold such data. Instead we are led to believe that each Turning begins anew. Now, I'll except that it is a soul memory device too as I mentioned above...although, soul memory seems a bit more complicated than MW input data.  It can't. That's really my whole point. The Columns Ter'angreal did something that all of our previous understanding of how it might work says it can't do. When there is and alternative explanation that doesn't require turning years of consensus on its ear, I prefer the alternative to trying to come up with a new explanation for how the ter'angreal works.  That's understandable. Although, our understanding has shown itself to be incomplete over the years as more of the world is revealed. We've had to push Jordan to reveal more of the world to us enabling us to arrive at new consensus. We have been given new data, so I see no reason why arriving at new conclusions is out of the norm.  You want simple, how about:  "It didn't happen! It was all in Aviendha's head, and probably as a result of Nakomi's interrogation/intervention."
