In AOTC (and I'm sure ROTS), the Jedi mention that the Dark Side clouds everything. My question is: Why can't the Jedi see through that cover? Is the Dark Side's "shroud" somehow invincible to the Light Side? Isn't there somebody (even Yoda, if anybody else) who could figure out a way to meditate and use the Force to see through the deception that the Dark Side creates? I just don't understand why the Light Side isn't able to remove the Dark Side's cover. I think it may have something to do with the fact that the Force is out of balance because of the Dark Side's presence, and that may have something to do with the Light Side's inability to see through the Dark Side, but I'm not sure.
