nice comments and thoughtful thread. :)
when i began meditating, i practiced the zazen techniques. but as i grew in my abilities i found that gradually i was able to try other techniques from different eastern practices, and even began making up some of my own. or combinations of things that had worked the best for me.
and then one day i realized that i could meditate all day long, in every moment, regardless of what i was doing. washing the dishes etc. this was because i had become used to the result that meditation is supposed to give, and it did not have anything to do with being asleep or in some trance (in most cases). but rather it was a lucid clarity that it gives. it's really a state of mind. a higher resolution for seeing the world.
i still take time out occasionally to meditate. but mostly i just concentrate on residing with my entire self in the moment, every moment, as the eternal thing that it is, as i go about my day. like yoda said, there is no trying, only doing.
as far as demons are concerned, i never really thought about it, as i had desposed of that concept long before i even began meditating. but i agree with satanus. demons are inside, not outside. if anything, meditation exorcises demons. it puts one in control of their *mind*. and the ego, the biggest demon of them all, cannot survive long when one lives in the moment with every bit of energy and consciousness they have.
peace,
