The way things appear to be and the way things are can be completely different. For instance, we might travel the same ten mile journey to work every day and feel convinced we know the countryside that we pass through. But how would it be if one day we walked that same route to work, instead of going by car or train. When we slow down we see things differently. The Buddha wants us to slow down. Not because being slow is necessarily a virtue in itself, but by not seeing the way things actually are, we misperceive life and make mistakes.
