It emphasizes that a mantra is not only devotional sound but also a Vedic science: its ending, syllable-count, seer (ṛṣi), and metre (chandas) are part of its sanctity and correct transmission.
Bhakti here is supported by precision: devotion becomes steady and fruitful when the mantra is preserved and recited according to its recognized Vedic identifiers (ṛṣi and chandas), ensuring faithful continuity of the tradition.
Chandas and Śikṣā/Vyākaraṇa-style technical markers are highlighted—syllable/phoneme count (dviśatārṇa), mantra-ending (hṛd-anta), and the assignment of ṛṣi and chandas used for correct recitation and ritual application.
