This song is about the limits of the nervous system as exhibited in humans. It deals with perception, or rather our primitive foundations which direct our senses.
As this relates to the lyrics of the song, we are basically being blinded constantly from the "truth", that is, the purpose of this thing we call reality. We are locked in this physical "shell". Obfuscation is the concealment of intended meaning in communication, making communication confusing, intentionally ambiguous, and more difficult to interpret. You can interpret this as a sort of Big Brother watching you, controlling the media and what knowledge you are permitted to gain, or, you can easily see that without some external force, we as organisms are inherently shielded from knowing everything that is going on around us, from a microscopic to macroscopic scale, due to the fact that we are only as good as evolution will allow, at this present time, which on a relative scale, is practically insignificant.
