व्यसनयौगपद्ये परवृद्धौ च मित्रमर्थयुक्तौ तिष्ठति ॥ कZ_०८.१.५९ ॥
vyasana-yaugapadye paravṛddhau ca mitram artha-yuktau tiṣṭhati
当灾祸同时发生、且对手日益强盛时,只要其利益得到妥善保障,盟友仍会保持同盟立场。
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.
