Mbh 12.91.1a

"'"Utathya said, 'If the deity of the clouds pours rain seasonably and the king acts virtuously, the prosperity that ensues maintain the subjects in felicity. That washerman who does not know how to wash away the filth of cloth without taking away its dye, is very unskilful in his profession. That person among Brahmanas or Kshatriyas or Vaisyas who, having fallen away from the proper duties of his order, has become a Sudra, is truly to be compared to such a washerman. Menial service attaches to the Sudra; agriculture to the Vaisya; the science of chastisement to the Kshatriya, and Brahmacharya, penances, mantras, and truth, attach to the Brahmana. That Kshatriya who knows how to correct the faults of behaviour of the other orders and to wash them clean like a washerman is really their father and deserves to be their king. The respective ages called Krita, Treta, Dwapara and Kali, O bull of Bharata's race, are all dependent on the conduct of the king. It is the king who constitutes the age.[269] The four orders, the Vedas and the duties in respect of the four modes of life, all become confused and weakened when the king becomes heedless. The three kinds of Fire, the three Vedas, and sacrifices with Dakshina, all become lost when the king becomes heedless. The king is the creator of all creatures, and the king is their destroyer. That king who is of righteous soul is regarded as the creator, while he that is sinful is regarded as the destroyer. The king's wives, sons, kinsmen, and friends, all become unhappy and grieve when the king becomes heedless. Elephants and steeds and kine and camels and mules and asses and other animals all lose their vigour when the king becomes unrighteous. It is said, O Mandhatri, that the Creator created Power (represented by the king) for the object of protecting Weakness. Weakness is, indeed, a great being, for everything depends upon it.[270] All creatures worship the king. All creatures are the children of the king.
