涅槃經遊意 1.72

1.72

問：有得名生死，無得名涅槃，則有得名無常，無得名為常，得無得還是常無常。云何捨常、無常而用得、無得耶？

Question: If having acquisition is named saṃsāra and non-acquisition is named nirvāṇa, then having acquisition is named impermanence and non-acquisition is named permanence; acquisition and non-acquisition are still just permanence and impermanence. Why discard permanence and impermanence to employ acquisition and non-acquisition?
