विकुक्षेस्तु महातेजा बाणः पुत्र प्रतापवान्।बाणस्य तु महाबाहुरनरण्यो महातपा:।।।।
vikukṣes tu mahātejā bāṇaḥ putraḥ pratāpavān | bāṇasya tu mahābāhur anaraṇyo mahātapāḥ ||
To Vikukṣi was born Bāṇa, mighty in splendor and power; and to Bāṇa was born Anaraṇya, great-armed and austere in discipline.
The son of Vikukshi was highly energetic and powerful Bana and to him was born the mighty-armed Anaranya of great renown.
Dharma integrates power with restraint: royal might (pratāpa) is paired with tapas (discipline), suggesting strength must be governed by self-control.
The dynastic list continues, highlighting qualities of successive ancestors to characterize the moral pedigree of the line.
Tapas (austerity/self-discipline) as a virtue that legitimizes and purifies worldly authority.
