This mind talk of Rawatism is such a bunch of crap and always was. It is just doublespeak for questioning the current dogma as spoken by Rawat and filtered down through the ranks. Critical thinking was not discouraged in other aspects of life. Even in the repressive days of yore, it was rather encouraged to decontruct or otherwise question the accepted precepts of the outsider society and its voices of authority. This was typical in nightly satsangs. Only when one dared to extend this to the beliefs of Rawatism, one was "in their mind". To be "in your mind" was simply to be insubordinate - to question the authority of Rawat. The use of this technique within the cult is nothing less than a form of thought control. This is continually apparent in the Cats Whisker's dialogues. They will trash every element of society - nothing is sacred - but they will never ever call into question one iota of anything that Rawat ever said. Why if they did, they would be "in their mind".Of course this notion is complicated somewhat by the actual practice of meditation. I don't know much about this on a academic level as some others here seem to, but from my own experience, the sitting-down practice of meditation focuses the part of your brain responsible for higher cognitive processes and indeed you are able to quiet your mind for awhile. Somehow this allows other neural circuits to become active, perhaps through sheer boredom or the act of intense concentration, and thus one enters another cognitive state. I imagine that also by attempting to concentrate on your breath or on a mantra while going about your day might keep you more focused and less apt to become aggitated as well. Personally I don't like being in so much control. I enjoy my emotions and don't want to repress them. In any case, meditating while being active, if it is even possible, definitely does not shut down your mind.
The use of the word mind for people not trying to push an agenda of thought control variously refers to either the higher cognitive processes of the human brain or simply the sum total of brain activity. The later definition would allow anything with a semblence of brain function to have a mind. So by a "normal" definition of the word, to have an inactive mind means to be brain-dead. Not my goal in life.
