Mīmāmsa Sūtra 01.01.24

utpattau vā'vacanāḥ syuḥ arthasyā tanni-mittatvāt ॥1-1-24॥

At the time of origination, or due to non-utterances - may be, because meaning is not the cause.

(Question is posed on the sentence formed by a collection of words and its capacity to convey the same meaning, even if the words are eternal.)
