De-stressing

The other day in a Mumbai local train, I saw a man writing down "Hare Ram Hare Krishna" over and over again in a notebook. He was murmuring the phrase in sync with the scrawling, and clearl y his concentration on the task was rather immense. Was this his way of de-stressing himself after a long arduous day? I really don't understand how concentration is connected with calmness and meditation.

As far as I'm concered, I'm just happy to put on songs of Simon & Garfunkel or Sigur Rós. The latter's 'svefn-g-englar' is THE song to listen to, when you want to relax! :)
