People can think that mindfulness meditation is complicated, but it’s actually very simple to describe.  The great thing is that anyone can start by practicing for just 5 minutes a day.  Even such a short break from the normal activity of the mind can make a big  difference. Paying attention, observing, on purpose, without judgment, to the gentle rhythm of our breathing, is a good place to start to develop this natural skill.

Observation,

giving bare attention to whatever you happen to be experiencing at a particular moment,

is meditation.
