Daṇḍanīti and the King as the Cause of Yuga-Order (दण्डनीतिः राजधर्मश्च युगकारणत्वम्)
वैदिकानि च कर्माणि भवन्ति विगुणान्युत । ऋतवो न सुखा: सर्वे भवन्त्यामयिनस्तथा
vaidikāni ca karmāṇi bhavanti viguṇāny uta | ṛtavo na sukhāḥ sarve bhavanty āmayinas tathā ||
Bhishma said: When Vedic rites are not carried out in the prescribed manner, they lose their efficacy and become deficient in merit. As a consequence, the seasons too cease to be pleasant; they turn generally joyless and become sources of disease.
भीष्म उवाच
Properly performed Vedic duties sustain harmony; when ritual and dharma are neglected or done incorrectly, their merit declines and the wider world reflects that disorder—manifesting as unpleasant, disease-bringing seasons.
In Shanti Parva, Bhishma instructs Yudhishthira on governance and dharma. Here he explains a chain of consequences: flawed performance of Vedic rites leads to a breakdown in auspicious conditions in nature, symbolized by unhealthy seasons.
