Daṇḍanīti and the King as the Cause of Yuga-Order (दण्डनीतिः राजधर्मश्च युगकारणत्वम्)
अशुभस्य यदा त्वर्ध द्वावंशावनुवर्तते | कृष्टपच्यैव पृथिवी भवत्यर्धफला तथा
aśubhasya yadā tv ardhaṃ dvāv aṃśāv anuvartate | kṛṣṭapacyā eva pṛthivī bhavaty ardha-phalā tathā ||
Bhishma said: When only half of what is inauspicious prevails—while two portions follow after the auspicious—then the earth yields grain only through ploughing and sowing; yet even then the harvest is but half: one half ripens into fruit, and the other half is destroyed. The teaching is that when adharma is diminished but not eradicated, prosperity becomes conditional and fragile—human effort bears results, yet loss still accompanies gain.

Educational Q&A
Even when evil is reduced and good predominates, lingering adharma still weakens outcomes: prosperity depends on effort and remains insecure, so society must actively uphold dharma to prevent loss alongside gain.
In Bhishma’s instruction in the Shanti Parva, he describes a condition of the world where auspiciousness is present but not complete; the land produces only through cultivation, and even then only half the crop succeeds while the rest is ruined—an image of moral imbalance affecting material welfare.
