vākyatāyogatas tasmānnityatvaṃ nopapadyate // caśabdānnāpi varṇebhyo bhinnaṃ sphoṭākhyaṃ vākyam iti sūcayati / tasya mīmāṃsakair eva nirastatvād iti bhāvaḥ /
Therefore, eternality is not possible due to the impossibility of [its] being a sentence. The particle 'ca' indicates that the sentence cannot be the sphoṭa [either], as something different from the letters, the idea being that this [concept] has been rejected by the Mīmāṃsakas themselves.
