Jesus said: ‘Let your yea; and your nay. nay.’ When the warrior takes on a commitment, he keeps his word.
Those who make promises they do not keep lose their self respect and feel ashamed of their actions. These people spend their lives in constant flight; they expend far more energy on coming up with a series of excuses to unsay what they said than the warrior of light does in honouring his commitments.
Sometimes he too takes on a foolish commitment which will in some way harm him. He does not repeat his mistake, but he nevertheless keeps his word and pays the price for his own impulsiveness.
