The teaching of Christ, 'Resist not evil', is a hint not to respond to inharmony. For instance a word of kindness, of sympathy, or an action of love and affection, finds response, but a word of insult, an action of revolt or of hatred, creates a response too, and that response creates still more inharmony in the world. By giving way to inharmony one allows inharmony to multiply. Where does all the great unrest and discord that one now sees pervading the world come from? It seems that it comes from the ignorance of this fact that inharmony creates inharmony, and that inharmony will multiply. If a person is insulted his natural tendency is to reply by insulting the other person still more. In this way he gets the momentary satisfaction of having given a good answer. But he has responded to that power which came from the other, and these two powers, being negative and positive, create more inharmony. 'Resist not evil' does not mean to take evil into oneself. It only means: do not return the inharmony that comes to you, as a person playing tennis would send back the ball with his racket. But at the same time it does not suggest that one should receive the ball with open hands.
