Mbh 5.181.3b

As regards this maiden, she hath been refused by me before knowing what the faults, productive of great evils, of the female sex are, who is there that would admit into his abode a woman whose heart is another’s and who (on that account) is even like a snake of virulent poison? O thou of high vows, I would not, even from fear of Vasava, forsake duty! Be gracious unto me, or do me without delay that which thou hast thought proper. This sloka also, O thou of pure soul, is heard in the Puranas, O lord, sung by the high-souled Marutta, O thou of great intelligence! The renunciation is sanctioned by the ordinance of a preceptor who is filled with vanity, who is destitute of the knowledge of right and wrong, and who is treading in a devious path.--Thou art my preceptor and it is for this that I have from love reverenced thee greatly. Thou, however, knowest not the duty of a preceptor, and it is for this that I will fight with thee. I would not slay any preceptor in battle, especially again a Brahmana, and more specially one endued with ascetic merit. It was for this that I forgive thee. It is well-known truth, gatherable from the scriptures, that he is not guilty of slaying a Brahmana who killeth in battle a person of that order that taketh up weapons like Kshatriya and fighteth wrathfully without seeking to fly. I am a Kshatriya stationed in the practice of Kshatriya duties. One doth not incur sin, nor doth one incur any harm by behaving towards a person exactly as that person deserveth. When a person acquainted with the proprieties of time and place and well-versed in matters affecting both profit and virtue, feels doubtful, as regards anything, he should without scruples of any kind, devote himself to the acquisition of virtue which would confer the highest benefit on him. And since thou, O Rama, in a matter connected with profit of doubtful propriety, actest unrighteously, I would certainly fight with thee in a great battle.
