I read an article in NewScientist last week about how this kind of thing makes one feel at peace. When we make decisions it introduces an element of stress because we have to think about whether or not we are making the right decision. When we do anything which makes us stand out from the crowd we risk being noticed, analysed, and judged, which also causes stress.
It seems that this is relaxing in part because knowing exactly what is required of you relieves stress, knowing that you fit in without having to think about it relieves stress, feeling you are a single part of a larger whole makes you feel accepted.
Apart from all that, closing your eyes alters your brain patterns and makes you feel chilled out.
Spot on . its one of the few minutes you don't have to think about what choice you are making. and do what you've been instructed to do (with free will to abandon it- thus eliminating the Fuck off reaction you'd have towards your boss telling you to bend over 4 times so your performance at work is considered a valid one )
Luftazure, is prayer always a concentrated thoughtless act? or do you sometimes get distracted by thoughts about the events of the day/week?
