Yes, it's a popular notion that the "human mind can only focus on one thing at a time" but it's blatantly untrue
It isn't exactly true but it isn't untrue. The human mind finds ways to simplify complex actions that require a lot of concentration and distil them to a simple easy to understand form.
First off, the "paying attention to everything at once" state described above is pretty much the opposite of a trance state.
It is known as an Overload induction. I like to think of it like a record player skipping a beat.
Actually paying attention to everything is the opposite, the attempt to do so causes the trance state because it is difficult-impossible to be ever aware.
You can claim all you want that you're "resistant to trance" and that you're "not bragging" but you're going to have a difficult time convincing me that you spend every minute of every day fully self aware and without any mental processes on autopilot
It is resistant to the type of trance trying to be reached during meditation. Which is caused by what I believe is called hyperawareness as well as my own subconscious aversion to it.
It isn't "showing off" because it isn't a good thing, it is actually a bad thing. The inability to stop thinking constantly is akin to the inability to rest your own mind and serves as a barrier to both meditation, hypnosis, and even ordinary slumber (I get sleep anxiety a lot)
I am very well aware of the subject but I don't want to bog it down with all the ins and out so I will say that yes it is possible to get around those issues.
Heck Asperger syndrome is a barrier to guided meditation but only because of the cookie cutter formulas involved in it (People with Asperger syndrome tend to take things literally, when guided meditation tends to be very metaphorical) and it can be worked around easily with the right mindset.
All I am saying is simply speaking meditation works, some people have to work on it more then others. It is more then possible for someone to go through meditation and get nothing out of it even if they come in with an open mind.
From what I've heard, even with active effort from experts it can take years before you will have any progress if ever!
Which is the second answer I am giving: Does meditation actually work? Sometimes no.
Ugh I am bogging it down, it has been so long since I've had this conversation that I'd take over the thread to have it. So I am going to stop myself.
