उदासीनश्चेन्मध्यमं लिप्सेत यतः शत्रुमतिसंदध्यान्मित्रस्योपकारं कुर्यादुदासीनं वा दण्डोपकारिणं लभेत ततः परिणमेत ॥ कZ_०७.१८.२७ ॥
udāsīnaś cen madhyamaṃ lipseta yataḥ śatrumatisaṃdadhyān mitrasyopakāraṃ kuryād udāsīnaṃ vā daṇḍopakāriṇaṃ labheta tataḥ pariṇameta
If the neutral seeks to obtain/attach the middle king—because, by aligning the enemy’s intentions (or by arranging the enemy’s policy), he may render service to one’s ally, or else secure a neutral who provides force-support (daṇḍa-upakāra)—then one should accordingly shift/adjust one’s posture (pariṇameta).
Adaptive realignment: when a neutral’s pursuit of the middle king can be leveraged to benefit your ally or gain force-support, adjust your diplomatic posture to exploit that opening.
A partner who can supply coercive capacity—troops, threat, punitive leverage—rather than mere goodwill.
