Ask any psychiatrist about this one. Someone who happily admits to their
own mental issues is usually quite sane!
A lot of people who don't have a diagnosed mental illness are no less
deluded, and not numb through medication, but instead completely
drugged up by their blissful ignorance.
There's three principle stages of the development of a soul. The first
is that paradise akin to that described in the Garden of Eden- innocent
but ignorant. The second is the rollercoaster emotional world which
constitutes life on Earth, brought about when we think we know best but
don't. The third is where we return individually and collectively to
that paradise, once again innocent, but innocent and experienced.
