Knowing the times means, if your ability is high, seeing right into things. If you are thorougly conversant with strategy, you will recognise the enemy's intentions and thus have many opportunities to win. You must sufficiently study this.

To Tread Down the Sword

"To tread down the sword" is a principle often used in strategy. First, in large scale strategy, when the enemy first discharges bows and guns and then attacks it is difficult for us to attack if we are busy loading powder into our guns or notching our arrows. The spirit is to attack quickly while the enemy is still shooting with bows or guns. The spirit is to win by "treading down" as we receive the enemy's attack.

In single combat, we cannot get a decisive victory by cutting, with a "tee-dum tee-dum" feeling, in the wake of the enemy's attacking long sword. We must defeat him at the start of his attack, in the spirit of treading him down with the feet, so that he cannot rise again to the attack.

"Treading" does not simply mean treading with the feet. Tread with the body, tread with the spirit, and, of course, tread and cut with the long sword. You must achieve the spirit of not allowing the enemy to attack a second time. This is the spirit of forestalling in every sense. Once at the enemy, you should not aspire just to strike him, but to cling after the attack. You must study this deeply.

To Know "Collapse"

Everything can collapse. Houses, bodies, and enemies collapse when their rhythm becomes deranged.

In large-scale strategy, when the enemy starts to collapse, you must pursue him without letting the chance go. If you fail to take advantage of your enemies' collapse, they may recover.

In single combat, the enemy sometimes loses timing and collapses. If you let this opportunity pass, he may recover and not be so negligent thereafter. Fix your eye on the enemy's collapse, and chase him, attacking so that you do not let him recover. You must do this. The chasing attack is with a strong spirit. You must utterly cut the enemy down so that he does not recover his position. You must understand how to utterly cut down the enemy.
