Interesting thought, WTWizard.
There is also the possiblility that one has to develop a certain trait or particular way of perceiving
before being allowed to glimpse the more esoteric teachings. One has to be "readied" and "prepared"
to receive them. Therefore, they are hidden in plain site. The unprepared will perceive these things
on a different level, but for those who have developed that certain level of wisdom and understanding
required, the deeper spiritual mysteries will be more visible.
