यत्परस्य दुर्बलं वीतहस्त्यश्वं दूष्यामात्यं कृतोपजापं वा तत्प्रभूतसारेणाभिहन्यात् ॥ कZ_१०.५.४९ ॥
yatparasya durbalaṃ vītahastyaśvaṃ dūṣyāmātyaṃ kṛtopajāpaṃ vā tatprabhūtasāreṇābhihanyāt
Whatever is the enemy’s weak point—whether his force is deprived of elephants and horses, or his minister is corruptible, or he has been suborned—he should strike that with superior strength and resources.
He treats compromised officials and suborned agents as exploitable vulnerabilities on par with material deficits (like loss of cavalry/elephants), making political penetration a legitimate axis of attack.
