We spend more time judging than we might think. This technique is about deliberately taking a step back from some of those almost unconscious judgements we make throughout the day.
This technique is best practiced outdoors, with things going on around you. As you are walking around, practice accepting the moment, and avoid making any judgements.
For example, when you walk past someone, try not to think thoughts like "he's short. I'm taller than him". Don't make any decisions or value judgements. Just accept everything that comes your way.
If you are able to do this for ten minutes, you end up in quite a peaceful state. Personally, it took me a few tries to practice this, but after I while I found myself feeling uplifted and really appreciating the walks when I thought this way.
