The Gaze in Strategy

You eye things in a sweeping, broad fashion. As for the two manners of seeing things, kan [observing] and ken [seeing], the eye for kan is strong, the eye for ken weak; seeing distant things as if they are close at hand and seeing close things as if they are distant is special to the art of fighting. Knowing your opponent’s sword and yet not in the least seeing it [not being distracted by insignificant movements] is important in the art of fighting. You must study this. The gaze is the same for single combat and for large-scale strategy.

It is necessary in strategy to be able to look to both sides without moving the eyeballs. You cannot master this ability quickly. Learn what is written here; use this gaze in everyday life and do not vary it whatever happens.
