Question: Can you quiet your mind?
Answer: NO. Unless if you are dead or brain dead.
You are unconscious, sleeping and yet your brain memory works non-stop. Everything, every minute details are recorded including your dreams, snore and what have you? Other humans cannot retrieve those hidden memories simply because of unknown cause and if ever you can retrieve if would be through hypnotism or through experiment.
Would you like scientist to experiment on your mental health and your mental ability, functions and what lies ahead beneath through the deepest scanning machine can penetrate to find out?
There are several scientific research on how our brain works and how through unconscious state still those experts can analyze and retrieve what transpires beyond. That experiment could be very costly. Scientists love that idea because they gain from it financially and because somehow they are obsessed with the "Nobel Peace Prize." You know... obsession is also a twisted works of the mind.
If the James Web giant telescope can see everything through the vast deep space of the galaxy, the milky way and the wormholes and dark black holes there is nothing that the MRI scanner cannot scan your brain and underneath those brain cells from medulla, cerebrum to the tiniest nerves,veins and lobes. Well, scanning of the brain is only ethical if the patient needs it (diagnostic purpose) otherwise the experimenter cannot use a patient as a guinea pig or derived information or data from the patient's brain just because you know some doctors are crazy collecting x-rays of skulls and human brains. (There are crazy doctors! Dr. PSYCHO).
Anyway, what peace there is in silence?
Give peace a chance even if once in a while.
For a moment take a snooze. You don't lose by snoozing. You gain a lot by taking a snooze. Maybe a year younger added from your old, weary mind. Rather, one year less from your actual original age. Naptime is what we need. It's your brain, its your mind you need to give a rest. Time to relax.
There are bigger games and bigger dreams. Your mind cannot cope up how huge, humongous, as in actually you cannot measure it as it is immense > the universe is. You wont measure infinity. It's impossible. RELAX. The mind game is over for now.
