Varṇa-dharma and Rājadharma: Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Outline (वर्णधर्म-राजधर्म-प्रश्नोत्तरम्)
दण्डेन नीयते चेदं दण्डं नयति वा पुनः । दण्डनीतिरिति ख्याता त्रीललॉकानभिवर्तते
daṇḍena nīyate cedaṃ daṇḍaṃ nayati vā punaḥ | daṇḍanītir iti khyātā trīl lokān abhivartate ||
毗湿摩说道：“凭借惩罚（daṇḍa），此世得以被引导并维持在正道之上；又或者，国王依此教诲，在民众之中设立刑罚。因此，此一学统被称为‘Daṇḍanīti’——以公正刑罚施行治理之学。其作用与范围遍及三界。”

Educational Q&A
Social order is maintained when authority applies daṇḍa (punishment/discipline) in accordance with śāstra; this principled administration of punishment is called daṇḍanīti, a foundational element of rājadharma.
In the Śānti Parva’s instruction on rājadharma, Bhīṣma explains to Yudhiṣṭhira why the science of governance is termed daṇḍanīti: it guides the world by enforcing discipline and enables the king to establish lawful restraint among subjects.
