Vipassana meditation is primarily an exercise in awareness. Emptying the mind is not as important as being mindful of what the mind is doing. If you are frantic and you can’t do a thing to stop it, just observe. It is all you. The result will be one more step forward in your journey of self-exploration. Above all, don’t get frustrated over the nonstop chatter of your mind. That babble is just one more thing to be mindful of.
