As far as i understand, traditionally, meditation isn't about simply shutting down your mind as a whole. it is about: 1) Concentration (shutting down NOISE) 2) Shutting down thoughts from one source (or chaotic sources) to open up your mind to a particular source (some traditions mean opening up to ur inner self while others mean opening up to a higher source) So the aim is to stop thinking random thoughts not for the sake of "no brain activity" but for a SPECIAL form of brain activity, which some traditions call "revelations"
