3.103

述曰：標無合體，謂於是喻處，若不言諸所作者皆無常，猶如瓶等，即不證有所作處無常必隨，即所作、無常不相屬著，是無合義。由此無合，縱使聲上見有所作，不能成立聲是無常，故若無合即是喻過。若云諸所作者皆是無常，猶如瓶等，即能證彼無常必隨所作性。聲既有所作，亦必無常隨，即相屬著，是有合義。

Commentary: Marking the substance of 'without application': it means that in the place of that example, if one does not say 'whatever is produced is impermanent, just like a pot etc.,' then one does not prove that wherever there is being produced, impermanence necessarily follows; that is, being produced and impermanence do not connect to each other. This is the meaning of 'without application.' Because of this lack of application, even if being produced is seen on sound, it cannot establish that sound is impermanent; therefore, if it is without application, it is a fault of the example. If one says 'whatever is produced is impermanent, just like a pot etc.,' then one can prove that impermanence necessarily follows the nature of being produced. Since sound has being produced, impermanence necessarily follows it as well, and they connect to each other; this is the meaning of 'with application.'
