4.67.6

snuṣāyā duhiturvāpi putre cātmani vā punaḥ |
atra śaṅkāṃ na paśyāmi tena śuddhirbhaviṣyati || 6 ||

"Arjuna said, 'Residing in thy inner apartments, I had occasion always to behold thy daughter, and she too, alone or in company trusted me as her father. Well-versed in singing and dancing, I was liked and regarded by her, and, indeed, thy daughter always regardeth me as her protector. O king, I lived for one whole year with her though she had attained the age of puberty. Under these circumstances, thyself or other men may not without reason, entertain suspicions against her or me. Therefore, O king, myself who am pure, and have my senses under control, beg to thee, O monarch, thy daughter as my daughter-in-law. Thus do I attest her purity. There is no difference between a daughter-in-law and a daughter, as also between a son and son's own-self. By adopting this course, therefore, her purity will be proved. I am afraid of slanderous and false accusations. I accept, therefore, O king, thy daughter Uttara as my daughter-in-law. Surpassing all in knowledge of weapons, resembling a celestial youth in beauty, my son, the mighty-armed Abhimanyu is the favourite nephew of Vasudeva, the wielder of the discus. He, O king, is fit to be thy son-in-law and the husband of thy daughter.'
