Mbh 12.121.2e

There is nothing more worthy of respect by kings than Chastisement by which the ways of Righteousness are pointed out. Brahman himself, for the protection of the world and for establishing the duties of different individuals, sent down (or created) Chastisement. There is another kind of Vyavahara arising out of the dispute of litigants which also has sprung from Brahman. Principally characterised by a belief in either of the two parties, that Vyavahara is seen to be productive of good. There is another kind of Vyavahara which has the Veda for its soul. It is also said to have the Veda for its cause. There is, O tiger among kings, a (third) kind of Vyavahara which is connected with family customs but which is consistent with the scriptures.[365] That Vyavahara which has, as above, been said to be characterised by a belief in either of two litigant parties, should be known by us as inhering in the king. It should be also known by the name of Chastisement, as also by the name of Evidence. Although Chastisement is seen to be regulated by Evidence, yet it has been said to have its soul in Vyavahara. That which has been called Vyavahara is really based upon Vedic precepts. That Vyavahara which has been indicated to have the Vedas for its soul is Morality or duty. It is also productive of good unto persons believing in duty and morality, men of cleansed souls have spoken of that Vyavahara as they have done of ordinary law.[366] The third kind of Vyavahara is also a preceptor of men, and it has also its roots in the Veda, O Yudhishthira! It upholds the three worlds. It has Truth for its soul and it is productive of prosperity. That which is Chastisement has been seen by us to be eternal Vyavahara. That which has been said to be Vyavahara is verily the Veda. That which is the Veda is morality, duty. That which is morality and duty is the path of Righteousness. This last it was which in the beginning had been Grandsire Brahman, that Lord of all creatures.
