Trying to make sense of chaos is human nature. Look at a blurry picture and your mind will try to 'piece it together' into something intelligible. And it's rewarding when it comes together. 'Aha!' However, say that picture is evidence of a crime. The criminal has a vested interest in keeping it obscure, whether that means burning the evidence or influencing your perception of the blur in question. When truth is an obstacle to one's ambition, lies are the only option, and that puts one at odds with anything truly human or spiritual in nature. It puts one in a position that goes against reality, forcing it into something it is not. Silencing those who question your manufactured reality - and thus risk waking others up to the truth and your own downfall - naturally follows.
This places those on the receiving end of the propaganda at a crossroads. It forces the questions: What do you truly value? Will you settle for being conned, if it means a relatively comfortable life? Or will you walk the 'thorny road of truth'? That is spirituality.
