स सार्णो दृश्यते यस्तु स मंत्रो दग्धसंज्ञकः । अस्रं द्वाभ्यां त्रिभिः षड्भिरष्टाभिर्दृश्यतेऽक्षरेः ॥ ३० ॥
sa sārṇo dṛśyate yastu sa maṃtro dagdhasaṃjñakaḥ | asraṃ dvābhyāṃ tribhiḥ ṣaḍbhiraṣṭābhirdṛśyate'kṣareḥ || 30 ||

It emphasizes that mantra-efficacy depends on correct phonetics and structure; certain phonetic marks and syllabic formations are treated as technical indicators for judging a mantra’s fitness in ritual use.
Even in devotion, the Purana upholds disciplined practice: bhakti expressed through japa and ritual should follow proper śikṣā (pronunciation) and mantra-lakṣaṇa so that worship is performed without technical faults.
Śikṣā and mantra-śāstra: it classifies mantras by observable phonetic marks (like sārṇa) and by akṣara-count patterns (2/3/6/8), a practical diagnostic used in correct recitation and ritual application.
