Daṇḍanīti and the King as the Cause of Yuga-Order (दण्डनीतिः राजधर्मश्च युगकारणत्वम्)
अशुभस्य यदा त्वर्ध द्वावंशावनुवर्तते | कृष्टपच्यैव पृथिवी भवत्यर्धफला तथा,उस समय पापके दो भाग पुण्यके दो भागोंका अनुसरण करते हैं। पृथ्वीपर जोतने- बोनेसे ही अनाज पैदा होता है; परंतु आधी फसलमें ही फल लगते हैं, आधी मारी जाती है
aśubhasya yadā tv ardhaṃ dvāv aṃśāv anuvartate | kṛṣṭapacyā eva pṛthivī bhavaty ardha-phalā tathā ||
अशुभस्य यदा त्वर्धं द्वावंशावनुवर्तते । कृष्टपच्यैव पृथिवी भवत्यर्धफला तथा ॥
