आपद्धर्मनिर्णयः — विश्वामित्र-श्वपचसंवादः
Apaddharma Determination: Dialogue of Viśvāmitra and the Śvapaca
अर्थयुकत्या हि जायन्ते पिता माता सुतस्तथा
arthayuktyā hi jāyante pitā mātā sutastathā
ビーシュマは言った。「まことに、目的と利益という理（ことわり）によって、父・母、そして同じく子という役割が成り立つ。すなわち、これらの関係は出生だけで理解されるべきではなく、果たすべき義務と目標という意味によって理解されねばならぬ。」
भीष्म उवाच
Educational Q&A
Bhīṣma emphasizes that family identities (father, mother, son) are not only biological labels; they are validated and made meaningful through artha-yukti—purposeful reasoning and the fulfillment of the duties and aims proper to each role.
In Śānti Parva, Bhīṣma is instructing Yudhiṣṭhira on dharma and right conduct. This line occurs within a didactic discussion where Bhīṣma frames social and familial relations in terms of their ethical function and intended purpose.
