Sama Veda — Pūrvārcika, Mantra 7
Agni as the gracious ritual guest—kindled, seated on the barhis, and invoked to grant welfare and carry offerings

{ "prastava": "(unspecified; would set a spacious tonal field)", "udgitha": "Majestic statement of Agni’s titles.", "pratihara": "Brief response emphasizing ‘ayam’ (this Agni) as immediacy.", "upadrava": "Flowing continuation ‘apāṃ retāṃsi jinvati’.", "nidhana": "Collective closure on ‘jinvati’.", "structure_notes": "The demonstrative ‘ayam’ can serve as a musical hinge between cosmic description and immanent action.", "singer_assignments": "Standard Sāmavedic roles." }
{ "gloss_summary": "mūrdhā = pradhāna/foremost among deities in sacrifice; Agni is first recipient. kakutpatiḥ = lord of the highest point/summit; his sovereignty extends over heaven and earth. apāṃ retāṃsi jinvati = he quickens the generative essences in the waters.", "ritual_interpretation": "Agni’s primacy in the rite is affirmed; by his presence the watery substances (including Soma and ritual waters) become potent and fruitful.", "theological_insight": "Agni is both transcendent (head of heaven) and immanent (this Agni here): cosmic order becomes accessible in the altar-flame.", "etymology_highlights": "mūrdhan (head) as foremost; kakut (peak) + pati (lord); retas as seed/creative essence; jinv (to quicken/enliven) as activation of potency." }
