ज्येष्ठ-कनिष्ठ-धर्मः — Duties of Elders and Juniors
Anuśāsana-parva 108
अपत्यमुत्पाद्य तत: प्रतिष्ठाप्प कुलं तथा
apatyam utpādya tataḥ pratiṣṭhāpya kulaṃ tathā
Bhīṣma dit : «Après avoir engendré une descendance, il faut ensuite établir et maintenir comme il se doit la lignée de la famille.»
भीष्म उवाच
The verse emphasizes gṛhastha-dharma: producing offspring is not the end of duty; one must also responsibly establish and sustain the family lineage through proper conduct, support, and continuity of dharma.
In the Anuśāsana Parva, Bhīṣma is instructing Yudhiṣṭhira on dharma. Here he states a household-oriented obligation: beget progeny and then ensure the stability and continuation of the kula.
