Just because it has been an evolutionary advantage for our mind to be constantly active, doesn't mean that this can't change.<p>That's the point of evolution: we adapt to what's necessary and, for millions of years, constant thought was the factor that made us smarter than everyone else, and the humans in whom this didn't occur weren't smart enough, thus their genes disappeared from the gene pool.<p>This, however, doesn't mean we can't keep evolving towards a state of consciousness where constant thought isn't required, it just means that -- as is always the case -- existence is challenging, because there's millions of years of inertia behind the mind. It has a strong pull, because it was needed for survival. But we can keep evolving.<p>It doesn't need to continue like this forever. It just means that, as opposed to earlier, the people in whom thought is too strong and uncontrollable are now the ones whose genes are removed from the gene pool, through mental illness and anxiety.<p>If you're willing to spend some time watching your mind, you'll realize that it already stops all the time, it's just a matter of noticing this, thus strengthening its absence. But don't expect there to be a button to push to make it stop. It was needed for survival, so its cessation has become associated with fear. But, while you are conscious of this fact, it's not a problem, just a challenge.
