व्यसनयौगपद्ये परवृद्धौ च मित्रमर्थयुक्तौ तिष्ठति ॥ कZ_०८.१.५९ ॥
vyasana-yaugapadye paravṛddhau ca mitram artha-yuktau tiṣṭhati
When calamities occur simultaneously, and when the adversary grows stronger, an ally remains aligned if its interests are properly secured.
Clear material interest and credible benefits (artha-yukti) that make staying preferable to defecting.
Allies may drift if not incentivized—especially when crises multiply and the enemy’s power rises.
