Mbh 12.67.2a

"'Bhishma said, "The (election and) coronation of a king is the first duty of a kingdom. A kingdom in which anarchy prevails becomes weak and is soon afflicted by robbers.[212] In kingdoms torn by anarchy, righteousness cannot dwell. The inhabitants devour one another. An anarchy is the worst possible of states. The Srutis declare that in crowning a king, it is Indra that is crowned (in the person of the king). A person who is desirous of prosperity should worship the king as he should worship Indra himself. No one should dwell in kingdoms torn by anarchy. Agni does not convey (to the gods) the libations that are poured upon him in kingdoms where anarchy prevails. If a powerful king approaches kingdoms weakened by anarchy, from desire of annexing them to his dominions, the people should go forward and receive the invader with respect. Some conduct would be consistent with wise counsels. There is no evil greater than anarchy. If the powerful invader be inclined to equity, everything will be right. If, on the other hand, he be engaged, he may exterminate all. That cow which cannot be easily milked has to suffer much torture. On the other hand, that cow which is capable of being easily milked, has not to suffer any torture whatever. The wood that bends easily does not require to be heated. The tree that bends easily, has not to suffer any torture (at the hands of the gardener). Guided by these instances, O hero, men should bend before those that are powerful. The man that bends his head to a powerful person really bends his head to Indra. For these reasons, men desirous of prosperity should (elect and) crown some person as their king. They who live in countries where anarchy prevails cannot enjoy their wealth and wives. During times of anarchy, the sinful man derive great pleasure by robbing the wealth of other people. When, however, his (ill-got) wealth is snatched by others, he wishes for a king.
