खनिधान्यभोगयोः खनिभोगः कोशकरः धान्यभोगः कोशकोष्ठागारकरः ॥ कZ_०७.११.१० ॥
khanidhānyabhogayoḥ khanibhogaḥ kośakaraḥ dhānyabhogaḥ kośa-koṣṭhāgārakaraḥ
खनिधान्यभोगयोर्मध्ये खनिभोगः कोशकरः, धान्यभोगः तु कोशकरश्च कोष्ठागारकरश्च ॥

It directly supports logistics—feeding troops and population—reducing vulnerability to market shocks and siege conditions.
