Most people seem to dedicate their lives to work and superficial pleasures rather than discovering truth. Obviously, a busy life leaves little time to find out about what is really going on in the world and whether or not spiritual forces have a role to play.
Those that seek out truth and then discover it is not in alignment with what the establishment teaches are often called "conspiracy theorists" or "truthers", frequently in a derisive way by those who fully accept the stories the establishment tells.
The one quality that is required to get to the truth of hidden matters is a passion for truth, beyond the desire to feel good, impress others, fit in or become wealthy, although these things don't need to be completely ignored.
Without this passion for truth, I believe the individual will end up living in a world of illusion, based on the lies the establishment tells to advance its selfish and often anti-human and anti-life agendas.
