मृदु-तीक्ष्ण-नीति तथा दुष्टलक्षण-विज्ञानम्
Measured Policy and the Recognition of Malicious Disposition
यथा वप्रे वेगवति सर्वतः सम्प्लुतोदके । नित्यं विवरणाद् बाधस्तथा राज्यं प्रमाद्यतः
yathā vapre vegavati sarvataḥ samplutodake | nityaṁ vivaraṇād bādhas tathā rājyaṁ pramādyataḥ ||
Bhīṣma said: Just as, when a torrent rushes with great force and water spreads everywhere, there is constant danger that the riverbank will split and collapse, so too a kingdom is continually at risk of ruin when its ruler is negligent.
भीष्म उवाच
A ruler must remain continually alert; negligence (pramāda) creates small breaches that quickly become irreversible collapse, just as a flood breaks a weakened embankment.
In the Shanti Parva’s instruction on kingship, Bhishma advises the king through a vivid simile: the state is like a riverbank under flood—only constant watchfulness and maintenance prevent ruin.
