कर्शनीयं वास्य मित्रं मध्यमो लिप्सेत प्रतिस्तम्भयेदेनं अहं त्वा त्रायेय इति आ कर्शनात् ॥ कZ_०७.१८.१२ ॥
karśanīyaṃ vā 'sya mitraṃ madhyamo lipseta pratistambhayet enaṃ ahaṃ tvā trāyeya iti ā karśanāt
Or the Madhyama may seek to acquire his ally who is fit to be worn down; he should keep him propped up with the promise, ‘I will protect you,’ until he is exhausted.
To convert an ally into a dependent: sustained but calibrated support prevents collapse while draining autonomy and bargaining power.
