The Gaze in Strategy
In strategy it is important to see distant things as if they were close, and to take a distanced view of close things. It is important in strategy to know the enemy’s sword and not to be distracted by insignificant movements of his sword. You must study this. The gaze is the same for single combat and for large-scale combat.
The gaze should be large and broad. This is the twofold gaze: “Perception and Sight.” Perception is strong and sight weak.
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.
