शब्दो ऽपि न मुख्यः को ऽपि वक्ति इति आगच्छन्त्या इव प्रतिश्रुत्कायाः श्रवणात्
Transliteration (IAST)
śabdo 'pi na mukhyaḥ ko 'pi vakti iti āgacchantyā iva pratiśrutkāyāḥ śravaṇāt
The sound too is not the real one, since the echo is heard as though coming from elsewhere, like (the impression) "someone is speaking."
