Meditation is not always a discipline which needs to be practiced solely in a seated, upright posture. From experience, the mind can be silent in the noisiest shopping mall or the loudest party. This does not mean we just miraculously stop thinking. It is almost impossible to completely curb our thoughts, even for a regular practitioner of meditation.
I recently watched a film - a terrible film - which had an archaic, grotesque depiction of life in a psychiatric ward. After I recovered from the boredom, I woke up, wiped dribble from my shirt, and then started to ponder over it. It was frustrating to think that people who have no experience of this kind of environment may be influenced by such a portrayal.
I am staying positive on the whole - it's actually not that bad, you just learn how to get on with it. I have had pretty bad luck; I appear to have had every side effect going to date. I won't go into the gory details but had a week of staring at hospital walls, barely recognising myself, unable to do anything being hooked up to a drip 24/7 and getting more and more down but even now I look back and think if that's the worst, I can deal with it.
