जायसा सम्भूययानमनर्थोऽर्थ इति संशयः ॥ कZ_०९.७.१२ ॥
jāyasā sambhūyayānam anartho'rtha iti saṃśayaḥ
Doubt arises whether undertaking a joint expedition with a victorious (stronger/successful) partner is harmful or beneficial.
A stronger partner may appropriate gains, dictate terms, or turn into a future threat; joint action can shift relative power against you.
In alliances, measure relative gain and postwar bargaining power, not just battlefield success.
