One should not be envious of someone who has prospered by unjust deeds. Nor should he disdain someone who has fallen while adhering to the path of righteousness. It is truly regrettable that a person will treat a man who is valuable to him well, and a man who is worthless to him poorly. One should have insight into this world of dreams that passes in the twinkling of an eye. With such a frame of mind, one will have divine protection even though he does not pray.
Intelligence is the flower of discrimination.
There are many examples of the flower blooming but not bearing fruit. No matter whether a person belongs to the upper or lower ranks, if he has not put his life on the line at least once he has cause for shame. If we watch men of other schools discussing theory, and concentrating on techniques with the hands, even though they seem skillfull to watch, they have not the slightest true spirit. Strategy is the craft of the warrior. Commanders must enact the craft, and troopers should know this Way.
