It emphasizes that mantra-power is tied to precise structure—especially beginning with Oṁ and correct syllable-count—showing that spiritual efficacy depends on disciplined Vedic phonetics and formulation.
By highlighting praṇava-led and properly measured mantras, it frames bhakti as guided devotion: reverence expressed through accurate recitation and authorized mantra-forms rather than mere emotion.
Śikṣā (phonetics) and mantra-chandas/akṣara-gaṇanā (syllable-count): the verse classifies mantras by their opening (praṇava) and by whether they are bīja-based or dvādaśākṣara (twelve-syllabled).
