Varṇa-dharma and Rājadharma: Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Outline (वर्णधर्म-राजधर्म-प्रश्नोत्तरम्)
धनुष्कोट्या महाराज तेन शैला विवर्धिता: । महाराज! सभी मन्वन्तरोंमें यह पृथ्वी ऊँची-नीची हो जाती है; उस समय वेनकुमार पृथुने धनुषकी कोटिद्वारा चारों ओरसे शिलासमूहोंको उखाड़ डाला और उन्हें एक स्थानपर संचित कर दिया; इसीलिये पर्वतोंकी लम्बाई
dhanurkoṭyā mahārāja tena śailā vivardhitāḥ | mahārāja! sarveṣu manvantareṣu iyaṃ pṛthivī ūncī-nīcī bhavati; tadā venakumāraḥ pṛthuḥ dhanurkoṭyā samantataḥ śilāsaṃghān utkhāṭya ekasmin sthāne saṃcicāya; tasmāt parvatānāṃ lambatā vistāraś ca ucchrayas ca vivardhata iti |
Sinabi ni Bhīṣma: “O dakilang hari, sa mismong dulo ng kaniyang busog ay napalago ang mga bundok. Sa bawat Manvantara, ang daigdig na ito’y nagiging hindi pantay—may mga bahaging umaangat at may mga bahaging lumulubog. Sa gayong panahon, si Pṛthu, anak ni Vena, ay nag-ugat at nagbunot ng mga tipon ng bato sa lahat ng panig gamit ang dulo ng busog at tinipon ang mga iyon sa iisang pook. Kaya’t lumaki ang haba, lapad, at taas ng mga bundok.”
भीष्म उवाच
A righteous king’s role is to restore order and stability when the world becomes disordered—even on a cosmic scale. Prithu exemplifies proactive governance: using power as a tool to reorganize nature for the common good, not for personal gain.
Bhishma explains that across different Manvantaras the earth becomes uneven. In such a period, King Prithu, son of Vena, uproots scattered rock-masses with the tip of his bow and piles them together, which results in mountains becoming larger in length, breadth, and height.
