Using a cellphone -- on the train (like in your photo) or elsewhere -- has become ubiquitous. While technology allows for immediate communication with others, sometimes I wonder if we have become too connected and accesible. Sure, all this connectivity can be genuinely helpful, but there are also negative consequences.
And maybe this is why turning off, logging off, meditating, clearing one's mind, or spending time away from all the actual and virtual noise becomes a necessity. It's a way of reconnecting with what's truly important.
