Just as one man can beat ten, so a hundred men can beat a thousand, and a thousand can beat ten thousand. - Miyamoto Musashi

Attitude is the spirit of awaiting an attack. You must appreciate this. In duels of strategy you must move the opponent's attitude. Attack where his spirit is lax, throw him into confusion, irritate and terrify him. Take advantage of the enemy's rhythm when he is unsettled and you can win.

I have climbed mountain Iwato of Higo in Kyushu to pay homage to heaven, pray to Kwannon, and kneel before Buddha. I am a warrior of Harima province, Shinmen Musashi No Kami Fujiwara No Genshin, age sixty years. From youth my heart has been inclined toward the Way of strategy. My first duel was when I was thirteen, I struck down a strategist of the Shinto school, one Arima Kihei. When I was sixteen I struck down an able strategist Tadashima Akiyama. When I was twenty-one I went up to the capital and met all manner of strategists, never once failing to win in many contests.

from one thing, know ten thousand things
