To lead uninstructed people to war is to throw them away.
Rotten wood cannot be carved.
Plan ahead or find trouble on the doorstep.
A man who does not think and plan long ahead will find trouble right at his door.
A knight whose heart is set upon the Way, but who is ashamed of wearing shabby clothes and eating coarse food, is not worth calling into counsel.
Success depends upon previous preparation, and without such preparation there is sure to be failure.
