I must say that the idea of the taint and seals together is intruiging, and the more of you you add your unique thoughts to this theory, the more convinced I become (And by the way, I'll be really mad if this is a correct theory because its the kind of thing you want to slowly figure out right before it is revealed.). But, I have my own addition to add to it. Today I read that the reason the seals are breaking is because the taint on saidin comes through them whenever a man channels. This, I think, is a very good theory. The seals began weakening, and because Rand was about to pop up, there were a bunch of false Dragons. All this channeling by false Dragons weakened the seals enough to let Aginor and Balthamel out. However, this is where I'm not sure my theory comes full circle: When Rand and Aginor are channeling at the Eye, Rand is not drawing from the Source that is driving at the Wheel, but the Pool of Purified Saidin. When I read the theory that the taint was eroding the seals, I immediately thought that Rand must have let all the Forsaken out by channeling so much saidin at the Eye, that the first seal (Hidden in the Eye) shattered. However, because the Pool of Saidin was purified, that first touch of Saidin at the Eye was the natural touch...therefore, would the taint be going into the Seal or not, at this touch? The Forsaken were all released somewhere near the end, or beginning of the first and second books, respectively.Therefore, some sort of small tension, from Rand, or the Dark One, cracked the seal. Whether channeling from the Eye caused the final breaking, or not, I am not sure. However, if channeling saidin without the Dark One's shield that stops the taint does erode the seals, then the last 3 or so seals are going to be going pretty fast with the 2 hundred or so Asha'man. Someone back me up, or disagree with me on this, because the more we pool our knowledge, and ideas, the more our theories take shape.
