In this modern world, we rush around all day, doing things, talking, sending and reading message. We are always on, always connected, always thinking, always talking. There is no   36   for stillness.

And when we are   37   to be still because we’re in line for something, or waiting at a doctor’s appointment, or on a bus or train, we often   38  something to do. Some will play with mobile devices, others will read something. Being still isn’t something we’re   39  .

This comes at a   40   : we lose that time for   41 , for observing and listening. We lose peace.

And   42   yet: sometimes too much action is worse than no action at all. You can run around crazily, but get   43  done.

Take a moment to think about   44   you spend your days. Are you constantly rushing around? Are you constantly reading and answering   45   checking on the news and the latest stream of information? Are you always   46   through your schedule?

Is this how you want to spend your   47   ? If so, peace be with you. If not, take a moment to be   48 . Don’t think about what you have to do, or what you’ve done already.   49   be in the moment.

Then after a minute or two of doing that, consider your life, and how you’d  

50   it to be. See your life with less movement, less doing, less rushing. See it with more stillness, more consideration, more   51   .

Then be that vision.

It’s pretty simple: all you have to do is sit still for a little bit each day.   52   you’ve gotten used to that, try doing less each day. Breathe when you feel yourself moving too   53  . slow down. Be present. Find happiness now, in this moment, instead of   54  for it.

55   the stillness. It’s a treasure, and it’s available to us, always.
