Can you totally clear your mind? How do you do it?

I can clear my mind for a few seconds and then I start laughing, or crying, or thinking of things how about you?

I read in an article that the key to relaxation is meditation, but you need to completely clear your mind for 30 minutes in order to meditate correctly. (I don't know how true that is.) Ever since I read it, I'll occasionally try to do so... I can't make it more than a minute or two at a time. My brain is too active, and there's too many distractions, or I start falling asleep. I don't think it would work even if I locked myself in an empty, soundproof room!Can you totally clear your mind? How do you do it?
Other than going to sleep not very long.





The slightest sound or sensation gets your mind going again.
