ഈ മന്ത്രം പത്തൊമ്പത് അക്ഷരങ്ങളാൽ സമ്പന്നം; അതിന്റെ അന്ത്യഭാഗം അഗ്നിദേവന് പ്രിയം. ഈ മന്ത്രത്തിന്റെ ഋഷി വരാഹൻ; ഛന്ദസ് ഗായത്രി, നിവൃത്-ആദി വിന്യാസത്തോടെ ആരംഭിക്കുന്നു.
Narada (teaching the technical mantra-lakshana within a Vedanga-oriented section; framed in dialogue with Sanatkumara tradition)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches mantra-lakṣaṇa—how a mantra is properly identified by syllable-count, ṛṣi, and chandas—so that recitation and ritual use align with Vedic order (vidhi) rather than mere sound.
Indirectly: by insisting on correct mantra identity (ṛṣi/chandas), it supports disciplined worship—devotion expressed through accurate, reverent recitation rather than casual repetition.
Chandas and mantra-śāstra basics: counting syllables (arṇa), assigning the seer (Varāha as ṛṣi), and identifying the metre (Gāyatrī), which are essential for correct Vedic chanting and ritual application.
