Noise

This one of the most helpful quotes I have ever found:

If my mind doesn't go out
to disturb the noise,
the noise won't disturb  me

Ajahn Chan

It is so easy to get distracted from practicing meditation by noise outside our meditation space, Sometimes we can even become angry and blame the noise for not being able to meditate.  If we accept the noises around us without anger and resentment we can continue with our practice without disturbance. I always begin a meditation by listening to the sounds around me without judgement as to whether the sound is good or bad.
