Silver Wind

Silver wind has 4 different components, not necessarily sequentially ordered.

'Ion' - Sense of balance, perspective and place in your surroundings.
A general way to increase to train 'Ion' is to blindfold yourself. Ion could also be described as using every sense but sight in order to paint a picture of your environment. Most people will find that as they can accurately judge small distances that are within arms reach, they will be able to better judge long distances.
'Rise' - Sense of change in the surroundings
Probably the most applicable to any kind of fighting, 'Rise' is how easily an accurately one can sense his surroundings change. Rise is essentially how often/easily your sense of "Ion" is altered, in other words, your sensitivity of 'Ion'. The only way I know of training a sense of 'Rise' is to go out on the beach on a dark night and to brace for impact against waves. This allows you to have a fairly constant change in "Ion", and also eliminates the interference of a human guessing what another human will do.
'Air' - Control and sense of timing.
Jumping rope helps train this one. Other things that might help include training on things that spin, and also hitting objects in time to a variable beat, somewhere along the lines of 60-200bpm.
'Verge' - Control of limits, self imposed and outer
Try this one last.
