大般涅槃經義記 4.9

4.9

Below, it clarifies the origin from which the two views arise: from permanence arises annihilation, and from annihilation arises permanence. Therein, first is the doctrine, next the metaphor, and last the application. In the doctrine, 'cultivating permanence falls into the view of annihilation' means that seeking permanence and failing to obtain it, one gives rise to the view of annihilation; 'cultivating all annihilation' means that the former holder of the view of permanence seeks annihilation and fails to obtain it, and therefore gives rise to the view of permanence. In the metaphor, 'moving the rear foot based on the front' means that the two views of annihilation and permanence alternate as prior and posterior. The application text can be understood.
