Quote by Thomas Merton

“The enemy must not know where I intend to give battle. For if he does not know where I intend to give battle he must prepare in a great many places,. And when he prepares in a great many places, those I have to fight in any one place will be few. For if he prepares to the front his rear will be weak, and if to the rear, his front will be fragile. If he prepares to the left, his right will be vulnerable and if to the right, there will be few on his left. And when he prepares everywhere he will be weak everywhere. One who has few must prepare against the enemy; one who has many makes the enemy prepare against him. If one knows where and when a battle will be fought his troops can march a thousand li and meet on the field. But if one knows neither the battleground nor the day of battle, the left will be unable to aid the right, or the right, the left; the van to support the rear, or the rear, the van. How much more is this so when separate by several tens of li, or, indeed, by even a few!”
