Shloka 68
Adhyāya 166: Kṛtaghna-doṣa (कृतघ्नदोषः) — the fault of ingratitude and the limits of expiation
परिवित्ति: परिवेत्ता या चैव परिविद्यते । पाणिग्रहास्त्वधर्मेण सर्वे ते पतिता: स्मृता:
parivittiḥ parivettā yā caiva parividyate | pāṇigrahās tv adharmeṇa sarve te patitāḥ smṛtāḥ ||
ビーシュマは言った。兄がまだ婚姻していないうちに弟が妻を迎えるなら、兄は「パリヴィッティ（parivitti）」、弟は「パリヴェッター（parivettā）」、そしてそのように迎えられた女は「パリヴィディヤテ（parividyate）」と呼ばれる。かかる婚姻はダルマに背いて行われるゆえ、関わる者すべてが正しさから堕するものとして記憶されている。

Educational Q&A
The verse teaches that violating the customary dharmic order of marriage—where the younger brother marries before the elder—constitutes an adharma-based marriage, and tradition regards all parties involved as incurring moral fault (patita).
In the Shanti Parva’s instruction on dharma, Bhishma defines technical terms used in dharma-discourse—parivitti (bypassed elder), parivettā (younger who marries first), and parividyate (the woman taken)—and states the ethical judgment attached to such a marriage.
