What is Rational? Can you Unthink?
Is it possible to not think about anything?
If it is, are there really stupid people around, whom are actually thoughtless? Or is this just how our judgment and our ego is telling us we don't agree with them?
If there is a "Rational mind", can you prove there is also an "Irrational mind", or are there only, "Irrational thoughts", which are simply ones we don't agree with?
The main way no thought exists, is if I fall asleep, or I try to figure out what some one else is thinking, but can't. On the other hand, some people have such active minds, that they are literally often thinking through 2 problems at a time. So it's probably not that big a deal if someone can not be thinking, but it doesn't matter, because if their not, they soon will be, otherwise they wouldn't be alive.
I practice meditation, but I have learned not to try to "destroy thought", but rather concentrate on breathing, or the mandala, as do the experts.
