राजद्रव्याणामन्यद्रव्येनादानं परिवर्तनम् ॥ कZ_०२.८.१६ ॥
rājadravyāṇām anyadravyenādānaṃ parivartanam
‘Parivartana’ is taking (state goods) by substituting them with other goods—i.e., exchanging/replacing state property with something else.
It is concealment-based theft: the offender masks removal by replacing with inferior/different items, complicating detection without inspection and valuation.
