Painful regulation is not to be held to, because that would lead to an impasse. Work through danger joyfully, take charge of the situation with discipline, get through with balance and rectitude. As heaven and earth are regulated, the four seasons take place. When laws are established with regulation, they do not damage property or injure people. Water over a lake, regulated.
Leaders establish numbers and measures, and consider virtuous conduct.
Without regulation there will be lament, but you cannot blame anyone. Peaceful regulation is successful. Contented regulation is auspicious. To go on will result in exaltation. Painful regulation bodes ill if persisted in.
