Mahabharata — Anushasana Parva, Shloka 66
Adhyāya 119: Vyāsa–Kīṭa-saṃvāda
Tapas-bala and karmic ascent across yoni
इक्ष्वाकुणा शम्भुना च श्वेतेन सगरेण च | अजेन धुन्धुना चैव तथैव च सुबाहुना
ikṣvākuṇā śambhunā ca śvetena sagareṇa ca | ajena dhundhunā caiva tathaiva ca subāhunā
毗湿摩说道：“（此一血脉/此一传统）由伊克什瓦库（Ikṣvāku）、商布（Śambhu）、施韦塔（Śveta）、萨伽罗（Sagara）所奉持；同样也由阿阇（Aja）与敦杜（Dhundhu），以及苏婆呼（Subāhu）所奉持。”

Educational Q&A
Ethical norms (dharma), especially for rulers, gain persuasive force when grounded in the conduct of revered predecessors; the verse appeals to lineage-based exemplars to reinforce continuity of righteous practice.
Bhīṣma is listing notable kings—Ikṣvāku, Śambhu, Śveta, Sagara, Aja, Dhundhu, and Subāhu—as authoritative exemplars, likely to support a point about established royal conduct or a long-standing tradition within a famed dynasty.
