Between mining revenue and grain revenue: mining yields cash to the treasury, while grain yields both treasury revenue and stocked granaries.
Mining primarily strengthens liquid finance (kośa), whereas grain strengthens both finance and physical provisioning through stored reserves (koṣṭhāgāra).
It directly supports logistics—feeding troops and population—reducing vulnerability to market shocks and siege conditions.
