Rishi: Bhṛgu-lineage (traditional attribution via internal mention of Bhṛgavaḥ); in Śukla-Yajurvedic liturgical use, treated as a received ṛṣi-tradition rather than a single author
Devata: Agni (as Hotṛ and first-established fire)
Chandas: Triṣṭubh (by RV-parallel cadence and length; confirmable by full metrical scan in RV source)
हा (अग्नी) येथे प्रथम धातृगणांनी स्थापन केला—होता, यज्ञांस अत्यंत योग्य, अध्वर-कर्मांत स्तुत्य. ज्याला द्रव्य-लाभ देणारा मानून भृगूंनी अरण्यात प्रकट केले—दीप्तिमान, सर्वव्यापी—प्रत्येक-प्रत्येक कुलासाठी.
