說無垢稱經疏 4.468

4.468

贊曰：此別問病源。有三：一問病根源、二問病來久近、三問滅位。久者遠。如者喻。此問意云：病生久近，喻如何等。

Commentary: This separately inquires after the origin of the illness. There are three: 1. inquiring into the root origin of the illness; 2. inquiring whether the illness's coming is long ago or recent; 3. inquiring about the stage of eradication. 'Long' means distant. 'Like' means an analogy. The meaning of this inquiry says: how long or recent has the illness arisen, and to what can it be analogized?
