Evolving (maturing) beyond one's "ordinary (birth) mind" would be like gaining access to and control over SIX additional fingers and TWO opposable thumbs. Where people are today, world over, in their ability to deal with the world, and themselves, in all its complexity, is like trying to build intergalactic space ships out of toothpicks and sealing wax... using just your (remember?) two pinky fingers.
It's NOT that people don't HAVE all 10 digits (or senses, for those of good memory), it's that the BEST EIGHT are totally occupied by meaningless, useless, extraneous motion/information. You know what that useless motion is? Attempting to fix, repair, modify, even destroy the "ordinary physical world". Just that, nothing more. What's so funny about it is, NOBODY ANYWHERE actually cares one damn bit about it, really, but ALL were taught from a young age to participate in that activity, so they do. They were suited up as a "worker bee" at a young and impressionable age, and for the rest of their growing up years and beyond the supposedly necessary "worker bee skills" (which are hardly that, but something much less!) were imprinted upon all of them. Now, they can not get free of them. Just look around.
And, it ain't easy (though it is simple when you know how) to distinguish between USELESS (unprofitable, inefficient) MIND ACTIVITY, and what "could be" called, Extraordinary Superman-like stuff, Genius Savant-like stuff. Now, there's lots that can be done with just two pinky fingers, even build rudimentary civilizations, institutions, and assorted junk none of us really need anyway - such as we have now on planet Earth - but THAT AIN'T NOTHIN'... Jeez, Louise, Wake Up Puhleeze!
