The sustainable community benefits by retreating with others of similar orientation when obstructions are too great. Forceful action by the sustainable community is bound to fail when circumstances combine to enhance the powers of seemingly minor hindrances. Disinterested restraining action by the sustainable community to ensure that the right prevails will eventually succeed, despite the real dangers with which such action is threatened. Relationships based on loyalty and trust reinforce the effectiveness of the sustainable community and of the complementary roles of those involved. When the sustainable community has achieved limited success from a position of weakness, it is dangerous to pursue the advantage any further until circumstances are more favourable.
Subtle restraints give rise to careful conduct.
