In a world full of uncertainty, what is the self? Am I merely a stream of consciousness, locked in the illusions of time and the material world around me? Is ther a God, or are we all part of some collective consciousness? And if so, what is the point to all of this madness? Does the truth, perhaps, lie in all of the beautiful madness is man really the center of the universe, or are we being watched and/or observed by some higher conscious being(s)?
