मित्रं चेन्न संधिमिच्छेदभीक्ष्णमुपजपेत् ॥ कZ_०९.६.१४ ॥
mitraṃ cenna saṃdhim icched abhīkṣṇam upajapet
If a friend does not wish to enter into an agreement, he should be persistently cultivated and persuaded (through continued approaches).
Continuous, low-friction diplomatic engagement—repeated messaging, inducements, reassurance, and relationship maintenance—until the ally becomes receptive.
