說無垢稱經疏 5.686

5.686

贊曰：此兩翻釋。初了都無有盡無盡，要究竟盡乃名為盡。即煩惱等究竟盡流，名為有盡。既究竟盡，不復更得常可有盡，則名無盡。有有盡則無無盡，無便無體，即有有盡，有盡亦無體，故都無二。

The Commentary says: This has two alternative explanations. First: comprehending that there is completely neither exhaustible nor inexhaustible, it must be ultimately exhausted to be called exhausted. That is, the ultimate stream of exhaustion of the defilements and so forth is called exhaustible. Since it is ultimately exhausted, it can no longer always be exhaustible, and is thus called inexhaustible. If there is the exhaustible, then there is no inexhaustible; non-existence then lacks substantial entity. That is, if there is the exhaustible, the exhaustible also lacks substantial entity; therefore there is completely no duality.
