5.155

論「然經說住異至異名住異」，通伏難也。難云：若經不說住相，何故彼經云住異相？通云：經說住異，即是此中異別名也。引例可知。

On the passage in the śāstra from “However, the sūtra speaks of the ‘difference of duration’…” to “…difference is called the ‘difference of duration’”: This resolves an implicit objection. The objection says: If the sūtra does not speak of the characteristic of duration, why does that sūtra speak of the “characteristic of the difference of duration”? The resolution states: What the sūtra calls the “difference of duration” is merely an alternative name for “difference” here. The cited analogy makes this evident.
