Do caged birds know they are prisoners?
How about fish in giant aquariums?
They have room to fly or swim, but not to fly as high or swim as far as they are meant to...
How would YOU know if your world is a small bubble of the possible universe that surrounds you?
You would simply start to "feel" as if something is "off"...like Neo waking up in The Matrix.
So keep asking questions...meditate...read interesting and fun books...know that "questioning" is a very good place to start.
I'm also happy to answer any specific questions you may have!
Meet two birds, Jake and Jerry.
They spend their days flying around in an aviary.
Jake enjoys where is and loves circling around and around,
But Jerry knows there's more, much more, "out there" to be found.
One day, Jerry sees his chance and finds a way out,
"This way Jake! This way Jake!" is what he would shout.
But Jake decided in the aviary to stay,
As Jerry took flight and soared away.
"You can say I'm driven by fear,
But out there is unknown...it's safer in here."
This was said by Jake, as back and forth he would pace...
Seeing Jerry fade into the sky with a big smile on his face.
