It points to a core Vedāntic-bhakti curriculum: Oṁ (Praṇava), principal Vaiṣṇava mantras (eight- and twelve-syllabled), and the mahāvākyas—showing that realization and devotion are grounded in authoritative Vedic utterances.
By highlighting the aṣṭākṣarī and dvādaśākṣarī mantras—classically used for Viṣṇu/Nārāyaṇa worship—it indicates bhakti as mantra-centered sādhana supported by Upaniṣadic meaning, not mere sentiment.
Mantra-prayoga depends on correct phonetics and recitation—linking directly to Śikṣā (pronunciation) and Vyākaraṇa (sound/word-forms) for preserving syllable-count (akṣara) and accurate chanting of Praṇava and the mantras.
