Holy Reading

Many times I ride the subway, there is someone reading the Torah or the Bible on the train, as part of their daily religious exercise. I always find it pretty fascinating: it requires concentration, as well as to be in a spiritual setting (or maybe it is just me), and to me, a quiet and more "isolating" place would be more adequate to a holy reading... I suppose those people are so much into their reading that they forget the rest (although how can one forget that he or she is not alone on top of a mountain but underground surrounded by dozens of persons...), and subway riders are many times so much in their own world anyway, "thanks" to their i-pod or video game, that it probably helps set those more religious people in their own world and closer to their God... I suppose this is just another way of saving any time available for busy (religious) New Yorkers...
