A simple practice in meditation.
In the following meditation, the emphasis is on breathing, but the underlying aim is to achieve a calm, non-judgemental awareness whereby your thoughts, feelings and sensations come and go without getting caught up in them. Sit in a relaxed position, close your eyes and straighten your back.
Concentrate on your breathing.
If external noises, thoughts, emotions or physical sensations catch your attention, let them go without getting carried away by them.
If you notice that your attention shifts to externals anyway, bring it back to your breathing and continue the exercise.
