Shloka 18
मृदु-तीक्ष्ण-नीति तथा दुष्टलक्षण-विज्ञानम्
Measured Policy and the Recognition of Malicious Disposition
दीर्घकालमपीक्षेत निहन्यादेव शात्रवान् | कालाकाडुशभक्षी हि क्षपयेद् यथा विश्रम्भमाप्तुयु:
dīrghakālam apīkṣeta nिहanyād eva śātravān | kālākāḍuśabhakṣī hi kṣapayed yathā viśrambham āptuyuḥ ||
毗湿摩说道：“即使等待很久，也当只是静观，伺机而动；但机会一到，便应当确实击倒仇敌。因为那‘以时为食’之人——懂得时机与忍耐者——能渐渐消磨对方，使其生出信任而松懈戒备；待取得其信任之后，便将之毁灭。”

Educational Q&A
The verse teaches strategic patience in rājadharma: one may delay action to secure the right time, allowing opponents to become complacent and trusting, and then decisively neutralize them. It highlights kāla (timing) as a decisive factor in political and military success, even when it involves calculated deception.
In the Śānti Parva’s instruction on kingship and governance, Bhīṣma advises Yudhiṣṭhira on dealing with hostile forces. He recommends waiting and observing until conditions are favorable, fostering the enemy’s sense of security, and then striking when the opportunity is assured.
