Dīkṣā, Mantra-Types, Mantra-Doṣas, and Qualifications of Ācārya–Śiṣya
माप्रा नमामि च पदं नास्ति यस्मिन्स कीलितः । एवं मध्ये द्वयं मूर्ध्नि यस्मिन्नस्त्रलकारकौ ॥ २८ ॥
māprā namāmi ca padaṃ nāsti yasminsa kīlitaḥ | evaṃ madhye dvayaṃ mūrdhni yasminnastralakārakau || 28 ||
In the word “māprā”, and likewise in “namāmi”, there is no letter that is ‘nailed down’ (i.e., marked as immovable). Thus, in the middle there are two, and at the head are those letters that function as technical markers (lakāra).

It emphasizes that accurate understanding of sacred words depends on technical śāstra (especially Vyākaraṇa/Śikṣā); correct linguistic analysis safeguards mantra-meaning and thus supports disciplined dharma and worship.
Bhakti is strengthened when names, prayers, and mantras are recited and interpreted correctly; this verse supports devotion indirectly by grounding worship in precise verbal knowledge (śabda-pramāṇa).
Vyākaraṇa-style analysis of letters within a word—identifying positions (beginning/middle) and the role of grammatical markers (indicatory signs) used for deriving correct forms and meanings.
