Becoming the opponent means you should put yourself in an opponent's place and think from the opponent's point of view. - Miyamoto Musashi

Whatever the Way, the master of strategy does not appear fast….Of course, slowness is bad. Really skillful people never get out of time, and are always deliberate, and never appear busy.

The gaze should be large and broad. This is the twofold gaze "Perception and Sight". Perception is strong and sight weak. 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.

"Being like a rock wall" is when a master of martial arts suddenly becomes like a rock wall, inaccessible to anything at all, immovable.
