Mbh 1.122.3

“It hath been heard by us that there was a great Rishi of the name of Uddalaka, who had a son named Swetaketu who also was an ascetic of merit. O thou of eyes like lotus-petals, the present virtuous practice hath been established by that Swetaketu from anger. Hear thou the reason. One day, in the presence of Swetaketu’s father a Brahmana came and catching Swetaketu’s mother by the hand, told her, ‘Let us go.’ Beholding his mother seized by the hand and taken away apparently by force, the son was greatly moved by wrath. Seeing his son indignant, Uddalaka addressed him and said, ‘Be not angry. O son! This is the practice sanctioned by antiquity. The women of all orders in this world are free, O son; men in this matter, as regards their respective orders, act as kine.’ The Rishi’s son, Swetaketu, however, disapproved of the usage and established in the world the present practice as regards men and women. It hath been heard by us, O thou of great virtue, that the existing practice dates from that period among human beings but not among beings of other classes. Accordingly, since the establishment of the present usage, it is sinful for women not to adhere to their husbands. Women transgressing the limits assigned by the Rishi became guilty of slaying the embryo. And, men, too, viol ting a chaste and loving wife who hath from her maidenhood observed the vow of purity, became guilty of the same sin. The woman also who, being commanded by her husband to raise offspring, refuses to do his bidding, becometh equally sinful.
